Compact, Reconfigurable Optical Delay Line on a Bent Silica Fiber
Manuel Crespo-Ballesteros, Misha Sumetsky
Tunable optical delay lines that simultaneously offer nanosecond-scale delay, broadband operation, low dispersion, and compact footprint remain challenging to realize with conventi…

Widely tunable SNAP microresonators via translation of side-coupled optical fibers
Isha Sharma, Misha Sumetsky
We demonstrate free spectral range (FSR) tunable Surface Nanoscale Axial Photonics (SNAP) microresonators induced by side-coupled parallel optical fiber segments. By translating on…

Widely FSR tunable high Q-factor microresonators formed at the intersection of straight optical fibers
Isha Sharma, Misha Sumetsky
We present a new class of high-Q tunable microresonators formed at the intersection of two straight silica optical fibers, whose free spectral range (FSR) can be widely tuned by fi…
