摘要： An apparatus for changing the direction of an optical beam comprises a thin film grating deflector; an optical energy source for providing optical energy to strike the deflector at a first angle with respect to gratings of the deflector and to exit the deflector at a second angle with respect to the gratings; and elements for applying a voltage to the deflector to vary the second angle. The optical energy source preferably comprises a laser diode; and a collimator for coupling energy from the laser diode to the grating deflector. The grating deflector is a planar waveguide including a plurality of stacked quantum wells formed of GaAs separated by barriers of AlGaAs. Optical energy provided to the grating deflector in a first direction is deflected in a second direction. These directions define a plane in which the waveguide is disposed. The quantum wells are stacked in a direction perpendicular to a plane of the waveguide. The optical energy source, the thin film grating deflector, the voltage applying elements and the collimator may be integrated into a single chip.

摘要： In a well-known semiconductor laser, a multiple quantum well type active layer consisting of barrier layers and active layers or well layers, each of which has a thickness less than the de Broglie wavelength of electrons, is doped with an impurity, and the impurity density is made higher in the barrier layer than in the well layer. Further, in a case where the multiple quantum well active layer is held between p-type and n-type cladding layers, the well layer is undoped, the part of the barrier layer lying in contact with the well layer is undoped, and the other part of the barrier layer close to the p-type cladding layer is put into the n-conductivity type while that of the barrier layer close to the n-type cladding layer is put into the n-conductivity type. Desirably, the impurity density should range from about 1.times.10.sup.18 to about 1.times.10.sup.19 cm.sup.- 3.
