IPC: H01S3/06
Filed: 1998-07-10
Abstract: PROBLEM TO BE SOLVED: To prevent a clock extractor in an optical pulse generator from being broken by the optical power of an optical pulse exceeding a rated power. SOLUTION: A ring resonator R generates an optical pulse having a high repeat frequency. A part of the optical pulse branched by an optical branching device 2 is branched from an optical branching device 8 to a protection device 20. An exciting light source 21 generates exciting light. An optical multiplexer 22 multiplexes the optical pulse from the optical branching device 8 and the exciting light. A rare earth element added optical fiber 23 is excited by the exciting light, and the exciting light power is adjusted so as to reach a saturated output. An optical switch 24 intercepts the optical pulse when the exciting light is not emitted or till a certain time elapses after emission. An optical attenuator 25 attenuates the optical power of the optical pulse from the optical switch to an optical power which can be received by a light reception element 10.  A clock signal extractor 9 extracts an electric clock signal from the optical pulse and finally outputs a clock signal CLK to an optical modulator 4. The optical modulator 4 modulates the intensity of light circulated in the ring resonator R to generate an optical pulse.

Filed: 1998-07-13
Abstract: PROBLEM TO BE SOLVED: To reduce errors accompanying averaging in finding a means square, to simplify the hardware and to reduce the cost by generating a digital signal expressing an electric signal, and generating the square digital signal of the digital signal by squaring this digital signal. SOLUTION: The mean square circuit 10 fetches the sample value of an electric signal 12 while using a standard analog/digital converter(ADC) 14 and generates a digital signal expressing that sample value. An output signal 34 of the ADC 14 is supplied to a square circuit 36. This square circuit 36 generates the stream of squared sample values by continuously squaring the adjacent sample values of the output signal 34 and makes an output signal 40 into square signal 38 of the electric signal 12. Then, a low-pass filter(LPF) 42 passes the DC component of the square signal 38 and removes all sinusoidal components through attenuation. Therefore, the LPF 42 generates the mean square at the level of desired accuracy determined by a roll-off ratio.
