This technology is a chip-scale photonics system supported by a large spectral range laser and a power-efficient light steering platform for extensive optical applications such as sensing, spectroscopy, and quantum processing.
Unmet Need: Flexible, low power consumption, small-footprint nanophotonic system
There are few suitable light sources to be integrated with chip-scale photonics as they have low spectral tunability and bulky external equipment. Additionally, current nanophotonic systems based on conventional silicon structures require substantial power consumption and have suboptimal beam steering performance due to environmental factors such as temperature. Coupling light propagation throughout nanophotonic platforms proves equally challenging because of tradeoffs between alignment tolerance, complexity, and power.
The Technology: Power-efficient nanophotonic architecture and integrated tunable laser
This nanophotonic platform supports an integrated tunable chip-scale laser and a low power-consumption light manipulation platform to achieve a broad spectral range performance covering the entire visible spectrum up to near-infrared. The broadband, narrow linewidth, and tunable lasing is achieved via commercially available laser diodes and optical resonators. The beam steering system is based on optical switch arrays and thus requires no moving parts and allows for straightforward calibration and material flexibility. Furthermore, built-in waveguide architectures such as micro-lenses and 3D polymeric funnels ensure robust control of optical signals’ alignment and spatial profile.
