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： A transmission device has a light emitting element for converting an electric signal to an optical signal and transmitting the same, and a drive section for outputting the optical signal from the light emitting element and driving the light emitting element by providing the electric signal to the light emitting element. The electric signal provided by the drive section to the light emitting element is a waveform deformed signal having a waveform in which a time required for a fall is longer than a time required for a rise in a binary signal having a signal of high level and a signal of low level.

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： An optical waveguide has a clad, a core surrounded by the clad and having an index of refraction larger than an index of refraction of the clad, an incident end face that makes light enter the core; and an exiting end face that makes light exit from the core. Two side faces of the optical waveguide are formed so as to have an angle change. The two side faces are translationally symmetric with each other, or two side faces excluding a portion of the side faces are translationally symmetric with each other.
