    The applications of micro-interferometer in optical communication


    Optical fiber communication is a rapid-growth industry in the past 25 years, for it provides enormous bandwidth, and the optical fiber is the only medium which can transport massive amounts of data over long distance. Combining the DWDM (Dense-Wavelength-Division-Multiplexing) technology and the coherent optical transmitter/receiver, the data capacity per fiber has reached more than 10 Tb/sec, commercially. To achieve such high capacity, optical interferometer plays an important role. In this talk, a few applications of the optical micro-interferometers in the telecom industry are reported.

    Speaker Bio(s): 

    Jay Hsieh is the founder of Goumax, working on the cutting-edge technologies for super-wide-band tunable laser source, infrared spectrometer and special interferometer for applications of optical test instrument and signal processing. Dr. Hsieh has been granted more than 30 US patents, in the area of optical communication and optical recording.

    From 2001 to 2015, Dr. Hsieh served as the President and Chief Technology Officer of Optoplex Corporation, in charge of developing optical devices for telecommunication network. He led the team to design and manufacture optical interleaver, TOADM (tunable optical add/drop module), OCA (optical channel analyzer) and DLI (delay-line interferometer). Those products enable to narrower the channel spacing, higher the data transfer rate, and enhance the flexibility of the networks.

    In years 2000 and 2001, Dr. Hsieh worked for Blaze Network Products as a director of Optical technologies, responsible for developing compact CWDM transceiver. From 1996 to 2000, Dr. Hsieh was in data storage industry. He was a research scientist of Komag Corporation and later jointed TeraStor Corporation as a recording system scientist, developing the technology of near field optical recording.

    Dr. Hsieh received his Ph.D. in Optics from Optical Science center, University of Arizona, Tucson, Arizona, and obtained the B.S and M.S. in Physics from National Tsing-Hua University, Taiwan.
