摘要：

This paper proposes and demonstrates a practical temperature-insensitive pressure sensor based on the simple reflective birefringence fiber interferometer which consists of only a polarization beam splitter (PBS), two segments of solid core polarization-maintaining photonic crystal fibers (PM-PCFs) with film reflector deposited on the far end of one of the PM-PCFs. We derived its spectrum response equation and the practical temperature insensitive lateral pressure sensor was designed and demonstrated experimentally.
