摘要：

We demonstrate a novel, compact and low-loss photonic crystal fiber modal Mach-Zehnder interferometer with potential applications to sensing and WDM telecommunications. By selectively collapsing a similar to 1-mm-long section of a hole next to the solid core, a pair of modes of the post-processed structure are excited and interfere at its exit. A modulation depth of up to similar to 13 dB and an insertion loss as low as 2.8 dB were achieved. A temperature sensitivity of -53.4 pm/degrees C was measured, making the device suitable for temperature sensing. (C) 2011 Optical Society of America
