The instant disclosure is directed toward integrated-optics-based composite phase controllers that include at least one thermo-optic (TO) phase controller and at least one stress-optic (SO) phase controller, each of which is configured to affect the phase, or other propagation characteristic, of a light signal travelling through a surface waveguide. The SO phase controller can induce a small phase change quickly, while the TO phase controller can slowly induce a larger phase change. Embodiments are particularly well suited for use in waveguide-based resonant elements, such as ring resonators, spectral filters, and the like. Furthermore, photonic systems comprising one or more composite phase controllers can be developed, such as wavelength-tunable lasers for applications such as LiDAR, chemical/biological sensing, medical diagnostics, and optical communications.

Integrated-optics-based composite phase controller operative for thermal-based and stress-based phase tuning of a surface waveguide

Aspects of the present disclosure describe systems, methods and structures including an integrated-optics-based externa-cavity laser configured for mode-hop-free wavelength tuning having an increased continuous tuning range with an ultra-narrow linewidth by increasing tuning sensitivity. Ultra-narrow linewidth is provided by extending cavity length with a multi-pass resonator based filter that may advantageously include tunable microring resonators that enable single-mode oscillation while contributing to the optical length of the laser with multiple passes of light through the ring(s) per roundtrip in the laser cavity. Further aspects of the present disclosure describe systems, methods, and structures exhibiting an enhanced 'tuning sensitivity'—defined by a continuous wavelength shift per induced cavity phase shift by a phase section. Such tuning sensitivity is increased by approximately a factor of 3 for synchronous tuning of phase section and ring resonators as compared to tuning phase section only.

Aspects of the present disclosure describe planar lightwave circuit systems, methods and structures including a resonant mirror assembly having cascaded resonators that provide or otherwise facilitate the control of the transmissivity/reflectivity of a planar lightwave circuit (PLC)&#x2014;or portion thereof&#x2014;over a range of 0% to substantially 100%.

An optical phonograph cartridge includes an optical vibration sensor that operatively couples to a stylus/cantilever to convert, to optical signals, mechanical vibrations representative of the music encoded in the groove of a vinyl record. The optical vibration sensor includes a photonic integrated circuit includes an input waveguide network for conveying light and an output waveguide network for conveying modulated light, wherein the modulated light is generated by a screen that is attached to the cantilever and is disposed between the input and output waveguide networks.
