    • Input data (101) on A and input data (102) on B are processed. First nonlinear conversion is made for the input data (101) on side A with a first key parameter (111). The exclusive-OR of the result (109) of the first nonlinear conversion and the input data (102) on side B appears as intermediate input data (106) to a sub-conversion processing portion (122) of the next stage on side B, while the input data (102) on side B undergo the second nonlinear conversion with a second key parameter (112) in the sub-conversion processing portion of the next stage on side A. The exclusive-OR of the result of this second nonlinear conversion and the intermediate data (106) is input as the intermediate data (108) to the sub-conversion processing portion (123) of the next stage on side B. The structures described above are cascaded, and the intermediate data in the final stages on sides A and B form the converted output data (103 and 104).

    • A pulse power source apparatus which quickly discharges the charged voltage of a capacitor (23) by closing a switch (24). First and second serial circuits (51 and 52) are connected in series between the output terminals of a DC voltage source (2). The first serial circuit (51) is composed of a first reactor (14) and a first forward diode (15), and the second serial circuit (52) is composed of a second forward diode (16) and the switch (24). A third serial circuit (53) composed of the capacitor (23), a second reactor (25), and a discharge tube (9), and the discharge tube is connected in parallel with the second serial circuit (52). When the switch (24) is closed, the discharge tube (9) emits light, but the discharged current from the capacitor (23) becomes an oscillating current and a voltage of the opposite polarity to that of the voltage generated at the initial charging time is generated in the capacitor (23). Since the oscillating voltage is superposed upon the power supply voltage and utilized at the next charging cycle time, an extremely efficient pulse power source apparatus can be obtained.

    • At least part of the layers of the waveguide of a laser, for example, for a DFB-LD, a waveguide including a first clad layer, an active layer, and a second clad layer of a second conductivity type, and, for a ridge type laser, a ridge formed on the remaining thickness of the second clad layer has a witdth such that light leaks out from the side walls of the waveguide formed in the light guiding direction. A case enclosing the side walls of the waveguide is provided, and a fluid having a prescribed refractive index is sealed in the case in such a way that the fluid is in contact with the side walls of the waveguide. The characteristic values of the laser can be adjusted easily. Therefore the laser having uniform characteristic values can be provided at a low cost. This laser is useful as a light source for wavelength multiplex transmission used for optical transmission, etc., of a main line system, such as a submarine cable.
