  1. ; (, 2021 IEEE 17th International Conference on Group IV Photonics (GFP))
    We demonstrate a high Q, compact photonic crystal nanobeam cavity in the new 45nm GlobalFoundries 45CLO monolithic electronics-photonics platform optimized for silicon photonics – with an intrinsic Q of 134,000, FSR of 24.17 nm, and a theoretical Q/V of 2.2E-5 (λ/n)^(-3).

  2. ; ; ; (, 2022 Optical Fiber Communications Conference and Exhibition (OFC))
    We demonstrate a scheme for microring resonators to operate as standing-wave resonators while eliminating reflections and maintaining traveling-wave-resonator-like through-port response, potentially enabling interdigitated p-n junction microring modulators to achieve higher performance than other junction geometries.

  3. ; ; ; ; ; ; (, Conference on Lasers and Electro-Optics, Technical Digest Series (Optica Publishing Group, 2022))
    We demonstrate device field characterization using NSOM collection and interaction measurement modes via the backside buried-oxide of large scale photonic circuits fabricated in monolithic electronics-photonics CMOS platforms (here a microdisk resonator) post-processed using flip-chip substrate-removal.

    null (Ed.)
    We report the first photonic crystal microcavity modulator realized in a foundry CMOS photonics platform. Bandwidth of 2.8 GHz and 5 Gbps data rate demonstrated utilizing an interdigitated p-n junction in a WDM compatible structure.

    null (Ed.)
    We report on microring modulators in the new 45CLO photonics-optimized 45 nm electronic-photonic CMOS platform. Interdigitated disk and vertical-junction rib microring de- signs are demonstrated, with 20 GHz bandwidth at 25 Gbps data rate.

  6. ; (, Frontiers in Optics / Laser Science)
    null (Ed.)
    We emulate the reflectionless response of a traveling-wave resonator using two bus-coupled photonic crystal nanobeam cavities with respective symmetric and antisymmetric modes. The scheme may enable new active device platforms beyond ring resonators.
