    A chip-scale laser platform based on silicon nitride ring resonators and commercial Fabry–Pérot laser diodes is developed for the wavelength range from 404 nm to 785 nm. The achieved coarse and fine tunings are up to 12.5 nm and 33.9 GHz, respectively, with kilohertz-scale linewidths and side-mode suppression ratios above 35 dB.

    A monolithic chip-scale ring laser gyroscope based on both Brillouin and Sagnac effects provides a sensitivity sufficient to measure sinusoidal rotations with an amplitude as small as 5 degrees per hour, thus enabling the first on-chip Earth rotation measurement.

    A Sagnac gyroscope based on Brillouin ring lasers on a silicon chip is presented. The stability and sensitivity of this on-chip planar gyroscope allow measurement of the Earth’s rotation, with an amplitude sensitivity as small as 5 deg h−1 for a sinusoidal rotation, an angle random walk of 0.068 deg h−1/2 and bias instability of 3.6 deg h−1.

    A unidirectional photonic wire laser has been developed by integrating reflectors into terahertz quantum cascade lasers. The transverse dimension is much smaller than the lasing wavelength (80 μm). A record wall-plug power efficiency of 1% is achieved.

    The self-organization of many laser modes in phase and frequency realized by minimizing radiation losses in a cavity enables the complex wavefront required to focus light scattered by turbid samples to be generated on sub-microsecond timescales without employing electronic feedback, spatial light modulators or phase-conjugation crystals.
