Wafer-scale fabrication of evacuated alkali vapor cells
Yang Li, Donggyu B. Sohn, Matthew Hummon +2
We describe a process for fabricating a wafer-scale array of alkali metal vapor cells with low residual gas pressure. We show that by etching long, thin channels between the cells…

Electrically driven linear optical isolation through phonon mediated Autler-Townes splitting
Donggyu Sohn, Oğulcan E. Örsel, Gaurav Bahl
Optical isolators are indispensible components in nearly all photonic systems as they help ensure unidirectionality and provide crucial protection from undesirable reflections. Whi…

Direction reconfigurable non-reciprocal acousto-optic modulator on chip
Donggyu B Sohn, Gaurav Bahl
Non-reciprocal components are essential in photonic systems for protecting light sources and for signal routing functions. Acousto-optic methods to produce non-reciprocal devices o…
