Temperature-compensating package for OH line filters for astronomy: II. manufacture, assembly, and performance study
Xijie Luo, Carlos E. Rodriguez Alvarez, Aashia Rahman +7
Multi-channel aperiodic fiber Bragg grating (FBG) based hydroxyl (OH) line filters have attracted significant interest in ground-based near-infrared (NIR) astronomical observations…
Athermal package for OH suppression filters in astronomy part 1: design
Carlos Enrique Rordriguez Alvarez, Aashia Rahman, Hakan Ãnel +3
We present the design of an athermal package for fiber Bragg grating (FBG)filters fabricated at our Institute for use in ground-based near-infrared (NIR) telescopes. Aperiodic mult…
