  • low loss and high Extinction Ratio strictly nonblocking 16 spl times 16 thermooptic matrix switch on 6 in wafer using silica based planar lightwave circuit technology
    Journal of Lightwave Technology, 2001
    Co-Authors: Takashi Goh, Akira Himeno, Masayuki Okuno, Kuninori Hattori, Mitsuho Yasu, Y Ohmori
    Abstract:

    We describe a silica-based 16/spl times/16 strictly nonblocking thermooptic matrix switch with a low loss and a high Extinction Ratio. This matrix switch, which employs a double Mach-Zehnder interferometer (MZI) switching unit and a matrix arrangement to reduce the total waveguide length, is fabricated with 0.75% refractive index difference waveguides on a 6-in silicon wafer using silica-based planar lightwave circuit (PLC) technology. We obtained an average insertion loss of 6.6 dB and an average Extinction Ratio of 53 dB in the worst polarization case. The operating wavelength bandwidth completely covers the gain band of practical erbium-doped fiber amplifiers (EDFAs). The total power consumption needed for opeRation is reduced to 17 W by employing a phase-trimming technique which eliminates the phase-error in the interferometer switching unit.

  • high Extinction Ratio and low loss silica based 8 spl times 8 strictly nonblocking thermooptic matrix switch
    Journal of Lightwave Technology, 1999
    Co-Authors: Takashi Goh, Akira Himeno, Masayuki Okuno, H Takahashi, Kuninori Hattori
    Abstract:

    This paper describes a silica-based 8/spl times/8 strictly nonblocking thermooptic matrix switch with a high-Extinction Ratio and low loss. We realized this matrix switch by using a configuRation which combines a double Mach-Zehnder interferometer (MZI) switching unit and an N/spl times/N matrix arrangement thus reducing the total waveguide length. The 8/spl times/8 matrix switch was fabricated on a 4-in wafer using planar lightwave circuit technology. We obtained an average Extinction Ratio of 60.3 dB and an average insertion loss of 5.1 dB. The operating wavelength bandwidth completely covers the gain band of practical erbium-doped fiber amplifiers (EDFAs).
