Low-loss, high-bandwidth fiber-to-chip coupling using capped adiabatic tapered fibers

May 1, 2020
Author(s)
Saeed Khan, Jeff Shainline, Richard Mirin, Sae Woo Nam, Sonia Buckley, Jeff Chiles
We demonstrate adiabatically tapered fibers terminating in sub-micron tips that are clad with a higher-index material for coupling to an on-chip waveguide. This cladding enables coupling to a high-index waveguide without losing light to the buried oxide. A

Second harmonic generation in GaAs-on-insulator waveguides fabricated at the wafer-scale

March 18, 2020
Author(s)
Eric J. Stanton, Jeff Chiles, Nima Nader, Galan Moody, Nicolas Volet, Lin Chang, John E. Bowers, Sae Woo Nam, Richard Mirin
Second harmonic generation (SHG) is demonstrated with unprecedented efficiency for a single-pass device. Modal phase-matching in GaAs-on-insulator waveguides is used to convert a 2.0 µm TE pump to a 1.0 µm TM signal with an efficiency of 40 W−1 in a length

Tunable quantum beat of single photons enabled by nonlinear nanophotonics

Author(s)
Qing Li, Anshuman Singh, Xiyuan Lu, John Lawall, Varun Verma, Richard Mirin, Sae Woo Nam, Kartik Srinivasan
Integrated photonics is a promising approach for scalable implementation of diverse quantum resources at the chip-scale. Here, we demonstrate the integration of two essential building blocks for quantum information science - quantum sources and frequency

Nonlinear Silicon waveguides produce tunable frequency combs spanning 2.0-8.5 ?m

September 25, 2019

Nima Nader, Abijith S. Kowligy, Jeffrey T. Chiles, Eric J. Stanton, Henry R. Timmers, Alexander J. Lind, Kimberly Briggman, Scott Diddams, Flavio Caldas da Cruz, Richard Mirin, Sae Woo Nam, Daniel M. Lesko
We present fully air clad suspended-silicon waveguides for efficient nonlinear interactions limited only by the silicon transparency. Novel fork-shaped couplers provide efficient input ( 2 dB) and broadband 3 dB output coupling spanning 6.0-8.5 υm

Multi-functional integrated photonics in the mid-infrared with suspended AlGaAs on silicon

September 18, 2019
Author(s)
Jeff Chiles, Nima Nader, Eric J. Stanton, Daniel Herman, Galan Moody, Biswarup Guha, Kartik Srinivasan, Scott Diddams, Ian Coddington, Nathan R. Newbury, Jeff Shainline, Sae Woo Nam, Richard Mirin, Jiangang Zhu, Juliet Gopinath, Connor Fredrick
The microscale integration of mid- and longwave-infrared photonics could enable the development of fieldable and reliable chemical sensors. The choice of material platform immediately determines the strength and types of optical nonlinearities available

Single-scan acquisition of multiple multidimensional spectra

May 29, 2019
Author(s)
Travis M. Autry, Galan Moody, James M. Fraser, Corey A. McDonald, Richard P. Mirin, Kevin L. Silverman
Multidimensional coherent spectroscopy is a powerful tool for understanding the ultrafast dynamics of complex quantum systems. To fully characterize the nonlinear optical response of a system, multiple pulse sequences must be recorded and quantitatively

Quantum Frequency Conversion of a Quantum Dot Single-Photon Source on a Nanophotonic Chip

Author(s)
Anshuman Singh, Qing Li, Shunfa Liu, Ying Yu, Xiyuan Lu, Christian Schneider, Sven Hofling, John Lawall, Varun Verma, Richard Mirin, Sae Woo Nam, Jin Liu, Kartik Srinivasan
Single self-assembled InAs/GaAs quantum dots are promising bright sources of indistinguishable photons for quantum information science. However, their distribution in emission wavelength, due to inhomogeneous broadening inherent to their growth, has

Paulina S. Kuo, Peter G. Schunemann, Mackenzie Van Camp, Varun B. Verma, Thomas Gerrits, Sae Woo Nam, Richard P. Mirin
We investigate parametric down-conversion in orientation-patterned GaP. Pumped at 865 nm, the signal and idler are at 1350 nm and 2400 nm, respectively.

Generating polarization-entangled photon pairs in domain-engineered PPLN

Author(s)
Paulina S. Kuo, Varun B. Verma, Thomas Gerrits, Sae Woo Nam, Richard P. Mirin
Using a periodically poled LiNbO3 crystal that is domain-engineered for two simultaneous type-II down-conversion processes, we demonstrated polarization-entangled photon-pair generation.

Integrated transition edge sensors on lithium niobate waveguides

Author(s)
Thomas Gerrits, Adriana Lita, Richard Mirin, Sae Woo Nam, Jan P. Hoepker, Stephan Krapick, Harald Herrmann, Raimund Ricken, Victor Quiring, Christine Silberhorn, Tim J. Bartley
We show the proof-of-principle detection of light at 1550 nm coupled evanescently from a lithium niobate waveguide to a superconducting transition edge sensor. The coupling efficiency strongly depends on the polarization, the overlap between the evanescent

Sonia Buckley, Adam McCaughan, Jeff Chiles, Richard Mirin, Sae Woo Nam, Jeff Shainline
We have previously proposed a novel hardware platform for neuromorphic computing based on superconducting optoelectronics that presents many of the features necessary for information processing in the brain. Here we discuss the design and training of
