Aperiodic phase masks for inscribing complex multi-notch OH-emission filters for astronomy
Kalaga Madhav, Ziyang Zhang, Martin M Roth
We demonstrate for the first time, a new type of aperiodic phase mask (APM) for fabricating multi-channel aperiodic fiber Bragg gratings. The mask is made of individual diffraction…
