Analog Photonics developed proprietary and patented integrated photonics technology on a CMOS-compatible 12” integrated photonics platform. Using a combination of silicon and silicon nitride as core waveguide layers our silicon photonics platform is low loss and can handle high optical power in the visible and near-infrared region of the electromagnetic spectrum. Having the capability to achieve both high, medium and low index contrast is at the basis of our state-of-the-art photonic components while maintaining a low footprint. The large temperature dependent refractive index of silicon enables highly efficient thermal tuning while the low temperature dependent refractive of silicon nitride enables temperature independent operation.
A phased array is an array of antennas which creates a beam of waves which can be electronically steered to point in different directions, without moving the antennas. Analog Photonics developed an efficient on-chip optical phased array solution working from the visible to near-infrared utilizing low-loss on-chip waveguides, phase shifters, and optical antennas integrated with on-chip germanium photodetectors and CMOS electronics. This non-mechanical beam steering technique is scalable to centime-scale apertures and works for both emitting and receiving operation.
