  • Optical switch and optical signal communication system
    Patent number: 8111989
    Abstract: An optical switch including a first reversible optical circulator and a second reversible optical circulator is provided. Each of the first reversible optical circulator and the second reversible optical circulator respectively has four I/O ports, wherein the four I/O ports are respectively a first terminal, a second terminal, a third terminal, and a fourth terminal, the four terminals sequentially transmit an optical signal in a forward circulation or a backward circulation according to a control signal, and an open end is formed between the first terminal and the adjacent fourth terminal. The open ends of the first reversible optical circulator and the second reversible optical circulator are coupled with each other.
    Type: Grant
    Filed: July 21, 2009
    Date of Patent: February 7, 2012
    Assignee: Industrial Technology Research Institute
    Inventors: Chun-Liang Yang, Dar-Zu Hsu, Jian-Ting Hong
  • Reconfigurable optical amplifier, reversible optical circulator, and optical signal transmission system
    Patent number: 8077385
    Abstract: A reconfigurable optical amplifier including a first reversible optical circulator and an optical gain device is provided. The first reversible optical circulator has four I/O ports which are respectively referred to as a first terminal, a second terminal, a third terminal, and a fourth terminal. The four I/O ports sequentially transmit an optical signal in a transmission direction of a forward circulation or a backward circulation according to a control signal. The first terminal is isolated from the adjacent fourth terminal. The optical gain device is connected between the first terminal and the adjacent fourth terminal. The second terminal and the third terminal are respectively connected to a first communication node and a second communication node.
