Errors in PDH offset locking due to spurious spectral features
Roame A. Hildebrand, Wance Wang, Connor Goham +2
The Pound-Drever-Hall (PDH) technique is widely used to stabilize the frequency of lasers. Here we report on a routinely underestimated source of error in PDH offset-locking: a shi…
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…
A radiofrequency voltage-controlled current source for quantum spin manipulation
D. S. Barker, A. Restelli, J. A. Fedchak +2
We present a design for a wide-bandwidth, voltage-controlled current source that is easily integrated with radiofrequency magnetic field coils. Our design uses current feedback to…
