We propose a different perspective that field enhancement can be interpreted as an elongation of effective length. Nonresonant waveguides and resonant cavities are bridged through this generalized effective length concept. @AdvPortfolio advanced.onlinelibrary.wiley.com/doi/10.1002/ad…

We demonstrate that the extinction ratio of the cavity resonance directly dictates FWM efficiency. This is the first systematic investigation of FWM conversion efficiency using pulley couplers in the gallium phosphide-on-insulator (GaP-OI) platform. opg.optica.org/oe/fulltext.cf…

We demonstrate a fast-response infrared (PbS) QD photodetector operating at 1550 nm wavelength and showcase the photodetector in acetylene gas absorption spectroscopy and high-Q tantalum pentoxide microresonator transmission spectrum characterizations. opg.optica.org/oe/fulltext.cf…

We propose a new design of gallium phosphide-oninsulator (GaP-OI) ring resonators using the Bezier curve bends. This geometry can not only reduce low sidewall scattering but also suppress mode crosstalk. #Best_Student_Paper_Award ieeexplore.ieee.org/document/11262… @IEEEPhotonics

We report a near-infrared photodetector based on Lead sulfide quantum dots. The device exhibits a broadband photoresponse across the 1460−1580nm range and a responsivity of 2.61mA/W at 1550 nm. ieeexplore.ieee.org/document/11262… @IEEEPhotonics

We propose a dual-core structure in shallow-etched Ta2O5 waveguides to engineer its dispersion profile, aimed for broadband supercontinuum generation (SCG). ieeexplore.ieee.org/document/11262… @IEEEPhotonics

We report the octave-spanning supercontinuum generation in a sub-millimeter GaP waveguide, featuring a figure of merit of 43.56 THz/mm/kW which is the highest among various integrated photonic platforms operating in the normal dispersion regime. nature.com/articles/s4146…

We demonstrate, for the first time, dual-polarization four-wave mixing (FWM) spectral translation in a Ta2O5 microring resonator. These results underscore the potential of Ta2O5 for doubling spectral capacity. opg.optica.org/oe/fulltext.cf…

Prof. Zhao received "Young Scientist Award" from IEEE OGC 2025. @IEEEPhotonics

This is the first design of PZT-actuated grating-embedded tantalum pentoxide microresonator. It will efficiently suppress high-order SBS at desired resonant wavelength owing to its frequency tuning capability. mdpi.com/2304-6732/12/9… @Photonics_MDPI

The GaP-OI resonator shows a temperature-dependent wavelength shift of 65.8 pm/K, allowing us to extract a TOC of 1.19 × 10^−4/K for GaP. This high temperature sensitivity empowers this platform well-suited for rapid thermal turning. @AppliedPhysLett pubs.aip.org/aip/apl/articl…

We demonstrate tantala Mach-Zehnder interferometer-based (MZI) athermal photonic devices using the structural compensation method, paving the way toward the realization of ultra-athermal integrated optical filters. ieeexplore.ieee.org/abstract/docum… @IEEEPhotonics #Photonics

Ta2O5 is a promising alternative to Si3N4 in integrated photonic applications. We show its potential in linewidth narrowing and demonstrate the first Ta2O5 external cavity self-injection laser at 1550 nm. @ACSPhotonics pubs.acs.org/doi/full/10.10…

We demonstrate an athermal Mach-Zehnder interferometer based on the structure compensation method in a tantalum pentoxide photonic platform. The asymmetric MZI has a TDWS of merely 1.98 pm/K, which is 4.6 times smaller than a regular MZI. #IPC2024 ieeexplore.ieee.org/abstract/docum…

Our conference paper received the Best Paper Award at the IEEE OGC conference. Tantalum pentoxide is a promising platform for integrated photonics. ieeexplore.ieee.org/document/10738… #OGC2024

We propose a new approach to delineate the spectral response of the interactions between the χ(2) and χ(3) nonlinearities, leading to asymmetric χ(2)-translated optical frequency combs at second-harmonic wavelengths. #OPG_OpEx opg.optica.org/oe/fulltext.cf…
