    Implementation Of A Loss-Compensated Recirculating Delayed Self-Heterodyne Interferometer For Ultranarrow Laser Linewidth Measurement
    Chen, X. P.; Han, M.; Zhu, Y. Z.; Dong, Bin; Wang, Anbo (Optical Society of America, 2006-12-01)
    Ultranarrow laser linewidth measurement using an optimized loss-compensated recirculating delayed self-heterodyne interferometer is described. An experimental setup is constructed to measure subkilohertz laser linewidths. The system parameters are optimized to obtain the best beat signals. The experimental results agree well with the theoretical analysis. Two methods of linewidth interpretation are presented and analyzed based on the experimental results. It is proved that a loss-compensated recirculating delayed self-heterodyne interferometer is an effective tool for measuring an ultranarrow laser linewidth. (c) 2006 Optical Society of America.

    Micro-Air-Gap Based Intrinsic Fabry-Perot Interferometric Fiber-Optic Sensor
    Chen, X. P.; Shen, F. B.; Wang, Z. A.; Huang, Z. Y.; Wang, Anbo (Optical Society of America, 2006-05-01)
    A simple intrinsic Fabry-Perot interferometric (IFPI) sensor is developed. The sensor is fabricated by two micro air gaps as reflective mirrors in a fiber to form a Fabry-Perot cavity. Theoretical and experimental studies of the sensor are described. Experimental results show that high resolution and high sensitivity can be achieved. Two structures of micro-air-gap-based IFPI sensors offer more applications than other IFPI sensors. (c) 2006 Optical Society of America.
