Abstract:
PURPOSE: An optical switch using a Mach-Zhender interferometer and an optical switch matrix including the same are provided to enhance a loss or a cutoff property by using an optical delay line which generates an optical length difference with the unit of a half wavelength. CONSTITUTION: The first coupler(120) splits an optical signal, transmitted to the first or the second input waveguides(113,114), into two optical signals. An optical delay line(140) includes the first and second female waveguides (141,142) transmitting the splitted optical signals, and generates an optical path difference with the unit of a half wavelength or one wavelength. The second coupler(130) splits each of the optical signals, outputted from the optical delay line, into two optical signals and transmits the splitted optical signals to the first or the second output waveguides(153,154).
