OCAQπ News

Excited to share that our work on photonic integrated ultra-narrow linewidth lasers at 780 nm has been published in Nature Scientific Reports.

Prof. Blumenthal and his group at UCSB are officially part of the University of Colorado led Q-SEnSE NSF QLCI (Quantum Leap Challenge Institute).

Our recent paper is ranked in the list of Photonics Research Top Downloads from July-September 2024.

Our journal publication entitled 'Anneal-free ultra-low loss silicon nitride integrated photonics' was selected by Light: Science & Applications (LSA) as the Top Downloaded Paper in August 2024.

Prof. Dawn Tan, Head of the Photonics Devices and Systems Group at the Singapore University of Technology and Design, has released a news article highlighting the impact of our "Anneal-free ultra-low loss silicon nitride integrated photonics" publication.

We report a significant advancement in high-performance integrated resonators based on a two-point-coupling design that achieves critical coupling simultaneously at multiple wavelengths across wide wavebands and tuning of the coupling condition at any wavelength, from under-, through critically, to over-coupled.

We report the lowest losses to date for an anneal-free process at a maximum temperature 250 °C

We are pleased to announce that our group has updated our name to OCAQπ, Optical Communications and Atomic Quantum Photonic Integration.

Please join the U.S. National Science Foundation Directorate for Engineering on April 2, 2024, from 3 p.m. to 4 p.m. Eastern for a Distinguished Lecture by Dr. Daniel Blumenthal of the University of California, Santa Barbara, on “Visible Light to Mid-Infrared Photonics for Atomic and Quantum Applications.”
