Abstract: PURPOSE:To reduce a noise due to astigmatism in the horizontal and vertical directions together with return light by dividing a waveguide structure in the interfacial direction of an active layer into two regions and gradually changing a waveguide structure of the junction part of two regions. CONSTITUTION:A semiconductor laser consists of an n-type Al0.45Ga0.55As layer 2, an Al0.15Ga0.35As active layer 3, a p-type Al0.45Ga0.55As layer 4, an n-type Al0.45Ga0.55As layer 5, an n-type Al0.55Ga0.45As layer 6, a p-type Al0.45Ga0.55As layer 8, a p-type GaAs layer 9, a p-electrode 10, an n-electrode 11 and a groove 12 on an n-type GaAs substrate 1. The layers 5 and 6 are current block layers. Since the layer 6 has a smaller refraction index than those of the layers 4 and 5, an effective refraction index in the horizontal direction of the active layer 3 is made large at the part of the groove 12. Further, width of a stripe 19 corresponding to the groove 12 gradually changes from the first region to the second region, the stripe 19 takes a wedge shape at the junction part 23 of two different horizontal mode guidewave structures for continuously changing from a gain guidewave to a gain guidewave plus a refraction guidewave.

Title: Method for correcting dark current for solid-state image sensor
Inventor: SUGANUMA ATSUSHI
IPC: H04N5/365
Filed: 1989-01-20
Abstract: PURPOSE:To remove light and dark unevenness in a reproduced picture and to obtain a high quality picture by correcting a read picture signal with a correcting signal when an original picture is read by a solid-state image sensor. CONSTITUTION:In an arithmetic and control circuit 46 of a signal correcting circuit 20, a correcting signal VC is calculated based on a picture signal VO, and the signal VC is stored in a memory 48. The signal VC stored in the memory 48 is introduced through a DAC 50 to the subtraction input terminal of an adder 34 as an analog signal VD. Picture information Vi photoelectrically converted by a CCD image sensor 18 is introduced through a switch 30 to the adder 34. In this case, since the signal VD is introduced to the adder 34, a picture signal VA introduced to a multiplying DAC 42 becomes a signal to hold only picture information from which a wavy output voltage characteristic caused by a dark current is removed. Consequently, for output of the circuit 20, the corrected high quality signal VO is outputted.
