چکیده
A chip-scale optical source with integrated beam steering is demonstrated. The chip was fabricated using the hybrid silicon platform and incorporates an on-chip laser, waveguide splitter, amplifiers, phase modulators, and surface gratings to comprise an optical phased array with beam steering across a 12° field of view in one axis. Tuning of the phased array is used to achieve 1.8°(steered axis)×0.6°(nonsteered axis) beam width with 7 dB background suppression for arbitrary beam direction within the field of view.

Hybrid silicon free-space source with integrated beam steering
Free-space beam steering using optical phase arrays are desirable as a means of implementing Light Detection and Ranging (LIDAR) and free-space communication links without the need for moving parts, thus alleviating vulnerabilities due to vibrations and inertial forces. Implementing such an approach in silicon photonic integrated circuits is particularly desirable in order to take advantage of ...

Free-space beam steering using optical phased arrays is a promising method for implementing free-space communication links and Light Detection and Ranging (LIDAR) without the sensitivity to inertial forces and long latencies which characterize moving parts. Implementing this approach on a silicon-based photonic integrated circuit adds the additional advantage of working with highly developed CM...

In this work we present the first fully-integrated free-space beam-steering chip using the hybrid silicon platform. The photonic integrated circuit (PIC) consists of 164 optical components including lasers, amplifiers, photodiodes, phase tuners, grating couplers, splitters, and a photonic crystal lens. The PIC exhibited steering over 23° x 3.6° with beam widths of 1° x 0.6°.
متن کاملOptimization of the Hybrid Silicon Photonic Integrated Circuit Platform
In the hybrid silicon platform, active III/V based components are integrated on a silicon-on-insulator photonic integrated circuit by means of wafer bonding. This is done in a self-aligned back-end process at low temperatures, making it compatible with CMOS-based silicon processing. This approach allows for low cost, high volume, high quality and reproducible chip fabrication. Such features mak...
متن کاملFully tunable microwave photonic phase shifter for broadband signals based on a single heterogeneously integrated III-V-on-Silicon microdisk resonator
We present a novel broadband microwave photonic phase shifter based on a single III-V microdisk resonator heterogeneously integrated on a silicon-on-insulator waveguide. Fully 2π phase shift tunability is accomplished by free-carrierinduced effective index modulation.
