Distance calibration via Newton's rings in yttrium lithium fluoride whispering gallery mode resonators

Josh T. Christensen, Farhan Azeem, Luke S. Trainor +2

In this work, we analyze the first whispering gallery mode resonator (WGMR) made from monocrystalline yttrium lithium fluoride (YLF). The disc-shaped resonator is fabricated using…

An ultra-stable microresonator-based electro-optic dual frequency comb

N. J. Lambert, L. S. Trainor, H. G. L. Schwefel

Optical frequency combs emit narrow pulses of light with a stable repetition rate. Equivalently, the generated light spectrum consists of many discrete frequencies spaced by this s…
