Fiber-to-waveguide alignment assisted by a transparent integrated light monitor [PDF]

, 2015
A novel fiber-to-waveguide alignment technique assisted by a transparent integrated light monitor is presented. The waveguide power is measured near the chip input facet by the contactless integrated photonic probe, which provides a feedback electrical ...

Silicon photonic integrated circuits

2016 Progress in Electromagnetic Research Symposium (PIERS), 2015
In this talk, we review the technical merits of silicon photonic devices and integrated circuits, which have benefited from high-index-contrast silicon waveguides, a high integration level of various optical functions on the same chips, and mature complementary metal-oxide semiconductor (CMOS) fabrication techniques.

Real-time fast physical random number generator with a photonic integrated circuit.

Optics Express, 2017
Random number generators are essential for applications in information security and numerical simulations. Most optical-chaos-based random number generators produce random bit sequences by offline post-processing with large optical components.

Scalable Integration of Long-Lived Quantum Memories into a Photonic Circuit

Physical Review X, 2015
We demonstrate a photonic circuit with integrated long-lived quantum memories. Precharacterized quantum nodes—diamond microwaveguides containing single, stable, negatively charged nitrogen-vacancy centers—are deterministically integrated into low-loss ...

Column-row addressing of thermo-optic phase shifters for controlling large silicon photonic circuits [PDF]

, 2020
We demonstrate a time-multiplexed row-column addressing scheme to drive thermo-optic phase shifters in a silicon photonic circuit. By integrating a diode in series with the heater, we can connect $N \times M$ heaters in an matrix topology to $N$ row and $

Design of an on-Chip Room Temperature Group-IV Quantum Photonic Chem/Bio Interferometric Sensor Based on Parity Detection

Nanomaterials, 2020
We propose and analyze three Si-based room-temperature strip-guided “manufacturable” integrated quantum photonic chem/bio sensor chips operating at wavelengths of 1550 nm, 1330 nm, and 640 nm, respectively. We propose design rules that will achieve super-

Towards on-chip generation, routing and detection of non-classical light

, 2015
We fabricate an integrated photonic circuit with emitter, waveguide and detector on one chip, based on a hybrid superconductor-semiconductor system. We detect photoluminescence from self-assembled InGaAs quantum dots on-chip using NbN superconducting ...
