摘要： A semiconductor laser drive apparatus comprises a bias current setting section (232) which sets a bias current value on the basis of the drive temperature so that the temperature characteristic of the bias current value with respect to the drive temperature may be a linear function having a slope except zero and a drive current setting section (233) for setting the drive current value on the basis of the drive temperature so that the temperature characteristic of the drive current value with respect to the drive temperature may be a function having a slope except zero. The temperature characteristic of the bias current and that of the drive current are functions different from each other. With this, low cost, space-saving, and power-saving of a semiconductor laser are achieved, and a semiconductor laser drive apparatus enabling a good transmission characteristic on the reception side and a high optical output over the whole drive temperature range when driving the semiconductor laser can be provided.

摘要： An optical cable module is mainly provided with: an optical waveguide (10), a light-receiving element (11) and a supporting substrate (14) at its end portion of the light releasing side. The end portion of the optical waveguide (10) is fixed in its relative positional relationship with the light-receiving element (11). The end face of the optical waveguide (10) is not made perpendicular to the light axis (X-axis), and is diagonally cut so as to form an optical path conversion mirror (10D). Assuming that a light ray (indicated by a solid line in the Figure) that passes through the center of the light-axis cross section of a core (10A), and is reflected by the optical path conversion mirror (10D), and then reaches a light-receiving face at a light axis reflection position, the center of the light-receiving element (11) is placed with a gap from the light axis reflection position, in the optical cable module (1).

摘要： A light transmission module includes an optical converter for converting an electrical signal to an optical signal; a light transmission path for transmitting the optical signal converted by the optical converter; an electrical transmission path for transmitting an input electrical signal; and a control instructing unit for instructing stop of drive to the optical converter based on a detection of an input electrical signal. When an input electrical signal having a predetermined frequency is detected, the input electrical signal having the predetermined frequency is converted to an optical signal and transmitted in the light transmission path. When input of an electrical signal other than the predetermined frequency is detected, the electrical signal other than the predetermined frequency is transmitted by the electrical transmission path without being converted to an optical signal due to the stop of the drive of the optical converter.
