Fractional optical angular momentum and multi-defect-mediated mode renormalization and orientation control in photonic crystal microring resonators

October 28, 2022
Author(s)
Mingkang Wang, Feng Zhou, Xiyuan Lu, Andrew McClung, Vladimir Aksyuk, Kartik Srinivasan
Whispering gallery modes (WGMs) in circularly symmetric optical microresonators exhibit integer quantized angular momentum numbers due to the boundary condition imposed by the geometry. Here, we show that incorporating a photonic crystal pattern in an

Exceptional points in lossy media lead to deep polynomial wave penetration with spatially uniform power loss

Alexander Yulaev, Sangsik Kim, Qing Li, Daron Westly, Brian Roxworthy, Kartik Srinivasan, Vladimir Aksyuk
Waves entering a spatially uniform lossy medium typically undergo exponential decay, arising from either the energy loss of the Beer–Lambert–Bouguer transmission law or the evanescent penetration during reflection. Recently, exceptional point singularities

Thermal release tape-assisted semiconductor membrane transfer process for hybrid photonic devices embedding quantum emitters

April 19, 2022
Author(s)
Cori Haws, Biswarup Guha, Edgar Perez, Marcelo Davanco, Jin Dong Song, Kartik Srinivasan, Luca Sapienza
Being able to combine different materials allows taking advantage of different properties and device engineering that cannot be found or exploited within a single system. In the realm of quantum and nanophotonics, for instance, one might want to increase

Ultra-broadband Kerr microcomb through soliton spectral translation

December 14, 2021
Author(s)
Gregory Moille, Edgar Perez, Jordan Stone, Ashutosh Rao, Xiyuan Lu, Tahmid Rahman, Yanne Chembo, Kartik Srinivasan
Broad bandwidth and stable microresonator frequency combs are critical for optical atomic clocks, optical frequency synthesis, dual comb spectroscopy, and a host of other applications that require accurate and precise optical frequency measurements in a
