Technology Portfolio

AOMicro's technology focus lies at the intersection of micromechanical and photonic structures. This unique combination of disciplines enables the incorporation of novel functionality in devices applicable to communications, sensing, and defense. Examples of past efforts highlighted below represent the core competence of AOMicro (a detailed publication list may be found here). These prototype devices include compact fast scanning tunable laser arrays (aimed at gas sensing and optical coherence tomography), amplifying tunable filters for fiber-based telecommunications, and hybrid micromachined optical-fiber-based physical sensors. From initial concept to final packaged die, AOMicro provides clients with a full spectrum of support.

Wavelength-Agile Laser Arrays

Integrating a suspended Bragg mirror with a vertical-cavity laser allows for wide and rapid wavelength tuning in a compact and low power source. These devices demonstrate MEMS-based emission tuning at a record short operating wavelength and utilize an innovative surface-micromachining process flow.

Tunable Optical Amplifiers

The presentation above provides an in-depth description of MEMS in III-V materials and features a cutting-edge resonant optical amplifier with a single-crystal GaAs actuator for cavity tuning. Operating at the telecom relevant wavelength range near 1550 nm, these amplifiers provide ~10 dB of fiber-to-fiber gain over a span exceeding 20 nm.
