| titleOfInvention | Wavelength interleaved bidirectional add/drop amplifier module with an arrayed-waveguide grating multiplexer |
| abstract | In the wavelength division multiplex optical fiber network, which is being studied recently, each node should have a function of adding or dropping a signal with an add / drop multiplexer.n n n Since the conventional unidirectional add / drop multiplexer can add / drop only signals in the same direction, two add / drop multiplexers are required for each node in order to transmit signals in both directions in the optical communication network.n n n The add / drop multiplexer proposed in the present invention simultaneously implements demultiplexing and multiplexing using a single N × N waveguide string lattice multiplexer. In addition, the wavelength of the signal is alternately allocated without using a separate bandpass filter to effectively remove the relative intensity noise through the transmission characteristics of the multiplexer. In addition, the proposed multiplexer can accommodate the increase of the signal capacity in the future by adding an inexpensive multiplexer and a demultiplexer without replacing an expensive N × N multiplexer. A bidirectional add / drop optical amplifier module is implemented by combining the bidirectional add / drop multiplexer and the optical amplifier. The bidirectional wavelength division multiple add / drop optical amplifier module according to the present invention has the advantage of being efficient and economical, and suitable for manufacturing a bidirectional wavelength multiplexing optical communication network. |
