Resumo
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 ∼1-mmlong section of a hole next to the solid core, a pair of modes of the postprocessed structure are excited and interfere at its exit. A modulation depth of up to ∼13 dB and an insertion loss as low as 2.8 dB were achieved. A temperature sensitivity of -53.4 pm/°C was measured, making the device suitable for temperature sensing. © 2011 Optical Society of America.
