摘要： A Raman excitation control method enabling to reduce the number of couplers and photodetectors (PD) for providing an optical transmission unit with reduced cost. The method is provided for use in optical amplification to amplify an optical signal using Raman excitation light fed into an optical transmission line. A backward light of a laser diode producing the Raman excitation light is monitored by an optical back power monitor. The monitored power value is compared with an initial set value stored in a memory for the laser diode. Based on this comparison result, a feedback control is performed against the light emission power of the laser diode.

摘要： An optical power monitor device capable of monitoring optical power with the influence of optical crosstalk eliminated, and an optical amplifier and an optical transmitter each having the monitor device. The monitor device is applied to a light source for outputting first and second beams, for example. The first beam is divided into first and second branch beams by a beam splitter. The first branch beam is supplied to a first photodetector. The first photodetector outputs a first signal having a level corresponding to the power of the first branch beam. The second beam from the light source is supplied to a second photodetector. The second photodetector outputs a second signal having a level corresponding to the power of the second beam. The first and second signals are supplied to a first subtracter. The first subtracter outputs a first error signal corresponding to the difference between the first and second signals. The first signal and the first error signal are supplied to a second subtracter. The second subtracter outputs a second error signal corresponding to the difference between the first signal and the first error signal. Thus, the second error signal is obtained by using the first and second subtracters to thereby cancel a noise component caused by optical crosstalk and therefore eliminate the influence of optical crosstalk from the second error signal.

摘要： An object of the present invention is to provide a portable radio apparatus that obtains a high antenna performance without limiting the degree of freedom in the exterior and design of a main body of portable radio apparatus. A portable radio apparatus (1) includes a radiation element (14) disposed on a side opposite to a rear part (10a) of a housing (10) through a circuit board (11), and a plate conductor (16) disposed substantially in parallel to the circuit board (11) between the circuit board (11) and the rear part (10a) of the housing (10). With the provision of the radiation element (14) and the plate conductor (16), when the portable radio apparatus (1) is put on a metal plate (300), the radiation element (14) operates as a vertical passive element having an electrical length of λ/2 with the help of an image current caused by the metal plate (300), and also the plate conductor (16) operates as a counterpoise of the radiation element (14), to thereby obtain a higher antenna performance on the metal plate (300). Also, since no rib for separating the antenna element (13) of the portable radio apparatus (1) from the metal plate is required, the degree of freedom in the exterior and design of the portable radio apparatus (1) main body is not limited.
