Efficient, Compact and Low Loss Thermo-Optic Phase Shifter in Silicon
Nicholas C. Harris, Yangjin Ma, Jacob Mower +4
We design a resistive heater optimized for efficient and low-loss optical phase modulation in a silicon-on-insulator (SOI) waveguide and characterize the fabricated devices. Modula…
An integrated source of spectrally filtered correlated photons for large scale quantum photonic systems
Nicholas C. Harris, Davide Grassani, Angelica Simbula +7
We demonstrate the generation of quantum-correlated photon-pairs combined with the spectral filtering of the pump field by more than 95dB using Bragg reflectors and electrically tu…
Experimental demonstration of broadband Lorentz non-reciprocity in an integrable photonic architecture based on Mach-Zehnder modulators
Yisu Yang, Christophe Galland, Yang Liu +6
We demonstrate the first active optical isolator and circulator implemented in a linear and reciprocal material platform using commercial Mach-Zehnder modulators. In a proof-of-pri…
Broadband on-chip optical non-reciprocity using phase modulators
Christophe Galland, Ran Ding, Nicholas C Harris +2
Breaking the reciprocity of light propagation in photonic integrated circuits (PIC) - especially in the CMOS-compatible silicon-on-insulator platform - is a topic of intense resear…
