Spectrally-pure optical serrodyne modulation for continuously-tunable laser offset locking
Roame A. Hildebrand, Wance Wang, Connor Goham +2
The comb-like spectrum added to laser light by an electro-optic modulator (EOM) finds use in a wide range of applications, including coherent optical communication, atomic spectros…
Quadrature amplitude modulation for electronic sideband Pound-Drever-Hall laser frequency locking
J. Tu, A. Restelli, K. Weber +4
The Pound--Drever--Hall (PDH) technique is routinely used to stabilize the frequency of a laser to a reference cavity. Electronic sideband (ESB) locking, a PDH variant, bridges the…
Microheater hotspot engineering for repeatable multi-level switching in foundry-processed phase change silicon photonics
Hongyi Sun, Chuanyu Lian, Francis Vásquez-Aza +9
Nonvolatile photonic integrated circuits employing phase change materials have relied either on optical switching mechanisms with precise multi-level control but poor scalability o…
A compact and open-source microcontroller-based rapid auto-alignment system
Yanda Geng, Alan Tsidilkovski, Kevin Weber +3
Maintaining stable and precise alignment of a laser beam is crucial in many optical setups. In this work, we present a microcontroller-based rapid auto-alignment system that detect…
