Direct growth of crack-free stoichiometric silicon nitride on sapphire for wide-band photonics
Zhaohui Ma, Ashish Chanana, Zhiquan Yuan +5
Low-loss stoichiometric silicon nitride on oxidized silicon has emerged as the major wide-band photonics platform for nonlinear and quantum photonics. These films, deposited by low…
Automated Vector-Scanning Spectroscopy for Large-Scale Characterization of Single Quantum Emitters
William Eshbaugh, Ashish Chanana, Edgar Perez +13
The inherent spatial randomness and broad spectral heterogeneity of epitaxial quantum dots (QDs) -- one of the most mature classes of solid-state quantum emitters -- remains a majo…
Enabling atom-clad waveguide operation in a microfabricated alkali vapor-photonic integrated circuit
Rahul Shrestha, Khoi Tuan Hoang, Peter Riley +5
Integrating alkali atomic vapors with nanophotonic devices offers a scalable route to quantum technologies that leverage strong atom-photon interactions. While there have been many…
Integrated broadband optical isolator via dynamic rotating destructive interference
Kyunghun Han, Yiliang Bao, Junyeob Song +7
Photonic integrated circuits route and shape light on a chip, but back-reflections feed back into coherent on-chip lasers, destabilizing operation and corrupting signals. Robust op…
Multimode Nanobeam Photonic Crystal Cavities for Purcell Enhanced Quantum Dot Emission
Junyeob Song, Ashish Chanana, Emerson Melo +7
Epitaxial III-V semiconductor quantum dots in nanopthonic structures are promising candidates for implementing on-demand indistinguishable single-photon emission in integrated quan…
Laser injection locking and nanophotonic spectral translation of electro-optic frequency combs
Roy Zektzer, Ashish Chanana, Xiyuan Lu +2
High-resolution electro-optic frequency combs (EO combs) consisting of thousands to millions of comb teeth across a bandwidth between 1 GHz to 500 GHz are powerful tools for atomic…
Low-power, agile electro-optic frequency comb spectrometer for integrated sensors
Kyunghun Han, David A. Long, Sean M. Bresler +7
Sensing platforms based upon photonic integrated circuits have shown considerable promise; however, they require corresponding advancements in integrated optical readout technologi…
Integrated silicon optomechanical transducers and their application in atomic force microscopy
Jie Zou, Marcelo Davanco, Yuxiang Liu +3
This chapter describes the basic design, simulation, and fabrication for fully Si integrated, waveguide coupled, optomechanical force and displacement sensors. The approach of full…
Spectroscopy of 1.55 m PbS Quantum Dots on Si Photonic Crystal Cavities with a Fiber Taper Waveguide
M. T. Rakher, R. Bose, C. W. Wong +1
We use an optical fiber taper waveguide to probe PbS quantum dots (QDs) dried on Si photonic crystal cavities near 1.55 m. We demonstrate that a low density (m$^…
