Latest Patents

Van Rees holds a patent for an "Integrated-optics-based external-cavity laser configured for mode-hop-free wavelength tuning." This invention describes systems, methods, and structures that include an integrated-optics-based external-cavity laser designed for mode-hop-free wavelength tuning. The technology boasts an increased continuous tuning range with an ultra-narrow linewidth by enhancing tuning sensitivity. The ultra-narrow linewidth is achieved by extending the cavity length with a multi-pass resonator-based filter, which may include tunable microring resonators. These resonators enable single-mode oscillation while contributing to the optical length of the laser through multiple passes of light. Furthermore, the patent outlines an enhanced tuning sensitivity, defined by a continuous wavelength shift per induced cavity phase shift by a phase section. This tuning sensitivity is increased by approximately a factor of three for synchronous tuning of the phase section and ring resonators compared to tuning the phase section alone.
