The visibility variation of the mach-zehnder optical fiber interferometerdue to birefringences, input states of polarization and optical losses

복굴절, 입력 편광상태 및 광손실이 광섬유간섭계의 visibility에 미치는 영향

The output of the mach-zehnder optical fiber interferometer varies with birefringences existing in the figer arms. New equations experessing for the visibility of the mach-zehnder interferometer were derived in terms of a number of parameters related to the birefringences, the input SOP and the optical losses. Based on the equations the visibility of the interferometer was simulated in different cases. Some maximum visibility conditons were also presented.
