Title: Light-wavelength-division multiplexing having high density
Inventor: UEIN ETSUCHI NOTSUKUSU
IPC: H04J14/00
Filed: 1994-11-10
Abstract: PURPOSE: To enable optical connection and an optical communication network to use high-density optical wavelength division multiplexing(WDM) by simultaneously transmitting many optical signals by using a single light source. CONSTITUTION: Channel signals are made incident to the modulator 27 of a modulator array 26 through a lens 24. In addition, one or more data signals are supplied to the modulator 27 from an electronic circuit 28 through a line 29, modulated into channel signals, and reflected to the lens 24. The lens 24 collects various kinds of channel signals to a diffraction grating 18, recombines the signals into a single WDM optical signal which is reflected by the grating 18, and a pick-off mirror 14 reflects the WDM signal toward a lens 32.  When the WDM optical signal is reflected toward the lens 32, an unmodulated optical pulse signal from a light source 11 passes through the mirror 14, but, in order to enable the mirror 14 to reflect the WDM optical signal from the grating 18, the grating 18 or array 26 is inclined so that the WDM signal may return to the light source through the route on which the unmodulated pulse signal runs. The lens 32 collects the WDM signal to an optical transmission medium 34. Therefore, multiple channel WDM optical signals can be obtained by using only the single light source 11.
