Broadband Waveguide-Coupled Photodetectors in a Submicrometer-Wavelength Silicon Photonics Platform
Alperen Govdeli, Jared C. Mikkelsen, Engjell Bebeti +4
Advances in silicon (Si) photonics at submicrometer wavelengths are unlocking new opportunities to realize miniaturized, scalable optical systems for biophotonics, quantum informat…
Implantable silicon neural probes with nanophotonic phased arrays for single-lobe beam steering
Fu-Der Chen, Ankita Sharma, Tianyuan Xue +12
In brain activity mapping experiments using optogenetics, patterned illumination is crucial for deterministic and localized stimulation of neurons. However, due to optical scatteri…
Isotropic gap formation, localization, and waveguiding in mesoscale Yukawa-potential amorphous structures
Murat Can Sarihan, Alperen Govdeli, Zhihao Lan +8
Amorphous photonic structures are mesoscopic optical structures described by electrical permittivity distributions with underlying spatial randomness. They offer a unique platform…
Room-temperature waveguide-coupled silicon single-photon avalanche diodes
Alperen Govdeli, John N. Straguzzi, Zheng Yong +6
Single photon detection is important for a wide range of low-light applications, including quantum information processing, spectroscopy, and light detection and ranging (LiDAR). A…
Power-Efficient Silicon Nitride Thermo-Optic Phase Shifters for Visible Light
Zheng Yong, Hong Chen, Xianshu Luo +7
We demonstrate power-efficient, thermo-optic, silicon nitride waveguide phase shifters for blue, green, and yellow wavelengths. The phase shifters operated with low power consumpti…
