Title: Optical semiconductor element
Inventor: TOYAMA MASAKI
IPC: G02F1/025
Filed: 1998-01-30
Abstract: PROBLEM TO BE SOLVED: To enable the high-speed modulation operation of an optical semiconductor element and at the same time, to enable the high-efficiency coupling of the element with an optical fiber by a method wherein a window region removed of an optical waveguide layer is etched into a narrow mesa shape and the width or thickness of a clad layer is changed according to the spread of a light distribution. SOLUTION: An optical semiconductor device comprises a structure, wherein a radio wave absorption semiconductor light modulator and a distributed feedback semiconductor laser are monolithically integrated. A modulator region 16, an electrode isolation region and a windodw region 15 are etched into a narrow mesa shape to contrive a reduction in the parasitic capacitance of the optical semiconductor device, the region 15 turns to the emitting end surface of the laser and the width of a narrow mesa 14 spreads into a tapered form. Light propagates while it spreads in the region 15 having not a waveguide structure, but reflection and scatteing of the light are hardly generated on the end surface of the narrow mesa 14 because the width of the mesa 14 spreads in a tapered form toward the emitting end surface.  Accordingly, a unimodal outgoing light distribution is obtained without incurring a reduction in light output due to a scattering loss. As this result, the coupling efficiency of an optical fiber is as high as 50%.

IPC: G03G21/00
Filed: 1983-02-09
Abstract: PURPOSE:To start copying operation without any preprocessing and to shorten an overall copying time while shortening a first copying time by driving a timer after copying to take another copy within the set time. CONSTITUTION:When a copy switch 31 is operated, a control circuit 30 outputs a motor driving signal to drive a motor 19. The control circuit 30 inputs a signal indicating the rotation position of a photosensitive body as a synchronizing signal 21 by the rotation of the motor and outputs a control signal I0 for controlling a device and a conveyance system arranged around the photosensitive body 5. The control circuit 30 while performing above-mentioned control operates its incorporated timer 301 with a specifying key 34 after copying operation and performs preprocessing continuously from the completion of copying up to the set time of the timer 301. Thus, the copying preprocessing is omitted and the copying operation is started to shorten the first copying time when an original is replaced, shortening the overall copy time.
