Journal ArticleDOI
Microring resonator channel dropping filters
TL;DR: In this article, a method of coupling of modes in time was proposed to simplify both the analysis and filter synthesis aspects of these devices, and the response of filters comprised of an arbitrarily large dumber of resonators may be written down by inspection, as a continued fraction.
Journal ArticleDOI
On-chip generation of high-dimensional entangled quantum states and their coherent control
Michael Kues,Christian Reimer,Piotr Roztocki,Luis Romero Cortes,Stefania Sciara,Stefania Sciara,Benjamin Wetzel,Benjamin Wetzel,Yu Zhang,Alfonso Carmelo Cino,Sai T. Chu,Brent E. Little,David J. Moss,Lucia Caspani,José Azaña,Roberto Morandotti,Roberto Morandotti +16 more
TL;DR: This work demonstrates on-chip generation of entangled qudit states, where the photons are created in a coherent superposition of multiple high-purity frequency modes, and introduces a coherent manipulation platform with which to control frequency-entangled states, capable of performing deterministic high-dimensional gate operations.
Journal ArticleDOI
CMOS-compatible integrated optical hyper-parametric oscillator
Luca Razzari,Luca Razzari,David Duchesne,Marcello Ferrera,Roberto Morandotti,Sai T. Chu,Brent E. Little,David J. Moss,David J. Moss +8 more
TL;DR: In this article, a fully integrated, CMOS-compatible, multiple-wavelength source with high differential slope efficiency at only a few tens of milliwatts of continuous-wave power is presented.
Journal ArticleDOI
Ultra-compact Si-SiO 2 microring resonator optical channel dropping filters
Brent E. Little,James Foresi,Günter Steinmeyer,E.R. Thoen,Sai T. Chu,Hermann A. Haus,Erich P. Ippen,Lionel C. Kimerling,Wayne Greene +8 more
TL;DR: In this paper, a compact optical channel dropping filter incorporating side-coupled ring resonators as small as 3 /spl mu/m in radius is realized in silicon technology.
Journal ArticleDOI
Very high-order microring resonator filters for WDM applications
Brent E. Little,Sai T. Chu,P.P. Absil,John V. Hryniewicz,F.G. Johnson,F. Seiferth,D. Gill,Vien Van,O. King,M. Trakalo +9 more
TL;DR: In this article, high-order microring resonators with 1 to 11 coupled cavities are demonstrated, which exhibit low loss, flat top, and out-of-band rejection ratios that can exceed 80 dB.
