Ultrafast optical circuit switching for data centers using integrated soliton microcombs
Arslan Sajid Raja, Sophie Lange, Maxim Karpov +13
Networks inside current data centers comprise a hierarchy of power-hungry electronic packet switches interconnected via optical fibers and transceivers. As the scaling of such elec…
Monolithic piezoelectric control of soliton microcombs
Junqiu Liu, Hao Tian, Erwan Lucas +9
High-speed laser frequency actuation is critical in all applications employing lasers and frequency combs, and is prerequisite for phase locking, frequency stabilization and stabil…
Massively parallel coherent laser ranging using soliton microcombs
Johann Riemensberger, Anton Lukashchuk, Maxim Karpov +4
Coherent ranging, also known as frequency-modulated continuous-wave (FMCW) laser based ranging (LIDAR) is currently developed for long range 3D distance and velocimetry in autonomo…
Hybrid Integrated Photonics Using Bulk Acoustic Resonators
Hao Tian, Junqiu Liu, Bin Dong +4
Microwave frequency acousto-optic modulation is realized by exciting high overtone bulk acoustic wave resonances (HBAR resonances) in the photonic stack. These confined mechanical…
Packaged photonic chip-based soliton microcomb using an ultralow-noise laser
Arslan S. Raja, Junqiu Liu, Nicolas Volet +7
Photonic chip-based soliton microcombs have shown rapid progress and have already been used in many system-level applications, including coherent communications, astrophysical spec…
Double inverse nanotapers for efficient light coupling to integrated photonic devices
Junqiu Liu, Arslan S. Raja, Martin H. P. Pfeiffer +5
Efficient light coupling into integrated photonic devices is of key importance to a wide variety of applications. "Inverse nanotapers" are widely used, in which the waveguide width…
