Nettet26. apr. 2024 · Integrated ultra-low-loss resonator on a chip Authors: Joyce K. S. Poon Abstract Exquisitely low-loss optical resonators have thus far remained discrete. … Nettet31. okt. 2024 · Published: October 31, 2024 Abstract We design and demonstrate a compact, narrow-linewidth integrated laser based on low-loss silicon nitride waveguides coupled to a III-V gain chip. By using a highly confined optical mode, we simultaneously achieve compact bends and ultra-low loss.
