Fiber-coupled polarization independent liquid crystal Fabry-Perot tunable filter Academic Article uri icon


  • A polarization independent Fabry-Perot liquid crystal tunable filter coupled to an optical fiber is demonstrated using polarization diversity. Using a Wollaston prism, the beam splits into two orthogonal beams, while the polarization of one of the beams is rotated by 90 deg using a variable half wave plate. The two beams are then combined into an optical fiber. Tuning of unpolarized light over the range 720 to 800 nm is demonstrated. (C) 2014 Society of Photo-Optical Instrumentation Engineers (SPIE)
