Abstract :
A compact in-line interferometer is demonstrated by splicing a piece of two-mode photonic crystal fiber (TPCF) between single mode fibers (SMFs). The TPCF is homemade and simulated based on extracted real cross section. The temperatures and strain induced interference pattern shifts with sensitivities of −43pm/°C and −0.62pm/µε are experimentally monitored.
