摘要： A photo-detector array device integrated with a read-out integrated circuit (ROIC) monolithically integrated for a laser-radar image signal and a manufacturing method thereof are provided. According to the photo-detector array device, a photodiode and control devices for selecting and outputting a laser-radar image signal are simultaneously formed on an InP substrate, so that it is possible to simplify manufacturing processes and to greatly increasing yield. In addition, after the photodiode and the control devices are simultaneously formed on the InP substrate, the photodiode and the control devices are electrically speared from each other by using a polyimide. Therefore, a PN junction surface of the photodiode is buried, so that a surface leakage current can be reduced and an electrical reliability can be improved. In addition, a structure of the control devices can be simplified, so that image signal reception characteristics can be improved.

摘要： The present invention relates to a millimeter wave frequency band optical oscillator used for an oscillating frequency signal source of millimeter waves transmitted from a repeater to a wireless subscriber in a millimeter wave wireless subscriber communication system for a next-generation (i.e., 5th generation or less) very high speed wireless internet service, wherein a loop mirror and a pair of optical fiber grating mirrors are used. A wavelength fixed type and a wavelength tunable type optical fiber grating mirrors are connected in a serial manner to constitute a dual laser mode resonator capable of simultaneously oscillating two laser modes, which are appropriate to each wavelength. Therefore, it is possible to obtain a laser light source capable of an extremely high frequency (60 GHz or more) modulation by using beat phenomena between two laser modes.

摘要： Provided is a polarization division multiplexed optical OFDM transmitter. The polarization division multiplexed optical OFDM transmitter includes a data demultiplexer, a training symbol generation unit and an optical up-converter and polarization division multiplexing unit. The data demultiplexer divides a transmission signal into a plurality of groups. The training symbol generation unit allocates a plurality of training symbols for each OFDM data which is included in the respective multiplexed groups, and allocates repetitive data in a time domain for the respective training symbols for data of 0 to periodically appear for the respective training symbols in a frequency domain. The optical up-converter and polarization division multiplexing unit performs optical frequency band conversion and polarization division multiplexing on an output of the training symbol generation unit to output a polarization division multiplexed optical OFDM signal corresponding to a plurality of polarization components.
