A Strategic Si3N4 materials platform for Integrated Quantum and Nano Technologies (Made in Canada!) Abstract: Silicon nitride has recently gained a lot of interest within the photonic device community, because of its unique properties, as an attractive materials platform of choice for a wide range of applications including sensing, metrology, nonlinear optics, quantum information processing and telecommunications. We report on an optimization procedure for depositing low-loss silicon nitride films at temperatures of 760˚C and 820˚C using low-pressure chemical vapor deposition. They were characterized in terms of quality and compositional proximity to stoichiometric silicon nitride. Films deposited at 760˚C showed a higher stoichiometry, with a silicon-to-nitrogen ratio of 0.744, when compared to the 820˚C film, which had a ratio of 0.77. We found the film deposited at the lower temperature had a smoother surface and exhibited lower optical losses. We investigated the impact of film stress on the refractive index of the film and found that removing the backside nitride from the wafer after deposition has a major effect on refractive index values. When using these films for integrated nonlinear and quantum applications, such as frequency conversion or soliton generation, knowledge of how the index changes with wafer and fabrication processing is critical for predicting the correct geometries, and the concomitant group velocities, needed to realize such quantum technologies. The measured losses from fabricated devices showed that our nitride material is comparable to the leading foundries if not better than them regarding the film quality and losses. ------------------------------------------------------------------------ Une plateforme stratégique de matériaux Si3N4 pour les technologies quantiques et nano intégrées (fabriquée au Canada !) Résumé : Le nitrure de silicium a récemment suscité beaucoup d'intérêt au sein de la communauté des dispositifs photoniques, en raison de ses propriétés uniques, en tant que plate-forme matérielle attrayante de choix pour un large éventail d'applications, notamment la détection, la métrologie, l'optique non linéaire, le traitement de l'information quantique et les télécommunications. Nous rapportons une procédure d'optimisation pour le dépôt de films de nitrure de silicium à faibles pertes à des températures de 760 °C et 820 °C par dépôt chimique en phase vapeur à basse pression. Ils ont été caractérisés en termes de qualité et de proximité de composition avec le nitrure de silicium stœchiométrique. Les films déposés à 760 °C présentaient une stœchiométrie plus élevée, avec un rapport silicium/azote de 0,744, par rapport au film à 820 °C, qui présentait un rapport de 0,77. Nous avons constaté que le film déposé à la température la plus basse avait une surface plus lisse et présentait des pertes optiques plus faibles. Nous avons étudié l'impact de la contrainte du film sur l'indice de réfraction du film et avons constaté que le retrait du nitrure arrière de la tranche après le dépôt avait un effet majeur sur les valeurs de l'indice de réfraction. Lors de l'utilisation de ces films pour des applications non linéaires et quantiques intégrées, telles que la conversion de fréquence ou la génération de solitons, la connaissance de la façon dont l'indice change avec le traitement de la plaquette et de la fabrication est essentielle pour prédire les géométries correctes et les vitesses de groupe concomitantes, nécessaires à la réalisation de telles technologies quantiques. Les pertes mesurées des appareils fabriqués ont montré que notre matériau nitrure est comparable aux principales fonderies, voire meilleur, en termes de qualité du film et de pertes.

With the growing demand for electric vehicles (EVs), efficient on-board charging systems have become imperative. Power Factor Correction (PFC) converters play a crucial role in enhancing the performance of these systems. By improving the power quality and efficiency of the charging process, PFC converters contribute significantly to EV charging infrastructure's overall functionality and reliability. PFC converters optimize the power factor by minimizing reactive power consumption, thereby reducing energy losses and enhancing the utilization of the electrical grid. This results in faster charging times and reduced operational costs for EV owners. Additionally, PFC converters help meet regulatory requirements for power quality and grid stability, ensuring seamless integration of EVs into existing electrical infrastructure. The integration of PFC converters in on-board charging systems enables EVs to draw power efficiently from various sources, including residential outlets and public charging stations. This versatility enhances the convenience and accessibility of EV charging, addressing concerns about range anxiety and infrastructure limitations. Furthermore, advancements in PFC converter technology, such as wide band gap devices (WBG) that include silicon carbide (SiC) semiconductors, offer higher efficiency and power density, further improving the performance of on-board charging systems. These innovations enable faster charging rates while reducing the size and weight of charging equipment, making EVs more practical and appealing to consumers. In conclusion, the implementation of PFC converters in on-board EV charging systems represents a significant step towards achieving efficient and sustainable transportation solutions. By optimizing power quality, improving efficiency, and facilitating rapid charging, PFC converters play a vital role in accelerating the adoption of electric vehicles and transitioning towards a greener future. The research examines the customized pulse width modulation (cPWM) based converter topologies for electric vehicle charging purposes. By using the proposed cPWM gating technique the device stress gets reduced which proportionally enhances the lifetime of the converter topology. The proposed unidirectional topology pursues the soft-switching behavior over full battery charging range and the voltage spikes across the rectifier diodes are also mitigated with proper selection of switches at a particular frequency. This phenomenon enhances the efficiency of the converter in a cost-effective way.

Abstract: Strongly-driven nonlinear optical processes such as spontaneous parametric down-conversion and spontaneous four-wave mixing can produce multiphoton nonclassical beams of light which have applications in quantum information processing and sensing. In contrast to the low-gain regime, new physical effects arise in a high-gain regime due to the interactions between the nonclassical light and the strong pump driving the nonlinear process. Here, we describe and experimentally observe a gain-dependent group delay between the multiphoton pulses generated in a high-gain type-II spontaneous parametric down-conversion source. Since the group delay introduces distinguishability between the generated photons, it will be important to compensate for it when designing quantum interference devices in which strong optical nonlinearities are required.
