摘要： An integrated optical pickup device for a magnetooptical recording medium (e.g. a magnetooptical recording disk) and/or an optical recording medium (e.g. an optical recording disk) in which a plurality of focusing grating couplers are formed on an optical waveguide layer manufactured on a substrate. A light reflected from a magnetooptical disk or an optical disk is guided by the focusing grating couplers into the waveguide layer to be separated and to be converged therethtough. The converged lights are detected so as to produce a tracking error signal, a focusing error signal, and an information readout signal. The plural focusing grating couplers are fabricated at an identical location on the waveguide in a superimposed fashion. This increases the utilization efficiency of reflection light per each unitary area of the focusing grating couplers and hence the signals are obtained in a stable state. Between a semiconductor laser and a collimation lens, there is formed a composite beam splitter having two reflection surfaces. Reflection lights from the magnetooptical disk are respectively reflected by these reflection surfaces and are then received by photosensors. Analyzers are disposed respectively on front sides of the photosensors. The analyzers respectively have polarization directions orthogonal to each other. Each photosensor includes three-partition photodiode. The beam sizing method and the push-pull detection methods are used for detecting the focusing and tracking errors. The optical pickup device can also used to read data from an optical disk. A prism is disposed between a semiconductor laser and a collimation lens. The prism has two reflection surfaces. Reflection lights from a magnetooptical disk are respectively reflected by these reflection surfaces to be received by photosensors. On front sides of the photosensors, there are respectively arranged analyzers respectively having polarization directions orthogonal to each other.

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.
