Chip-scale photonics platform with integrated wavelength-tunable laser

This technology is a microdisplay that is comprised of only two necessary layers paired with an excitation infrared laser for use in biological systems, augmented reality, or any other display-necessary application.

For example, current state-of-the-art methods such as active matrix organic light emitting diode (AMOLED) displays require multiple sophisticated layers to manufacture, and microLEDs are, on the other hand, very expensive.

The Technology: Infrared-laser driven, simple, nonlinear microdisplay.

“Compact narrow-linewidth integrated laser based on a low-loss silicon nitride ring resonator” Opt Lett, 2017 Nov 1; 42(21): 4541-4544.

This technology is a laser cavity design that uses an integrated resonator as a cavity mirror for on-chip lasers.

Unmet Need: Compact, low-loss, integrated lasers with narrow linewidths.

Interferometers use beam splitters, mirrors, and detectors to superimpose light and achieve highly sensitive amplitude and phase readouts.

The Technology: Coupled asymmetric interferometer with optical scanning probe for nanophotonic detection.

Scanning probe laser ablation with nanoscale resolution.
