IPC: H01S5/343
Filed: 2000-07-05
Abstract: PROBLEM TO BE SOLVED: To improve optical characteristics of an active layer of a layer device by applying a semiconductor device to the laser device, to prevent propagation of defects such as APDs in the active layer. SOLUTION: A multilayered structure 19, disposed on a substrate 10 of a laser device, includes an n-type clad region 11 and an undoped optical guide region 12, 14 disposed on the n-type clad region 11. An active region 13 is disposed in the optical guide region 12, 14, and eventually a p-type clad region 15 and a p-type contact region 16 are disposed on the optical guide region 14. In this case, the active region 13, having only a single quantum well layer, is applied to a laser consisting of a plurality of quantum well layers and a barrier layers. The barrier layer 17 is formed between the substrate 10 and the active region 13. Due to this structure, APDs either will not reach the optical guide region 12, 14 at all or a reduced number of APDs will reach the optical guide region 12, 14, so that it results in the improvement of the characteristics of a laser device.

Title: Method and circuit for generating waveform
Inventor: ITO YOSHIKUNI
IPC: H04B7/26
Filed: 2000-07-10
Abstract: PROBLEM TO BE SOLVED: To provide a waveform generating circuit capable of reducing the capacity of a ROM for band limit filter for generating a transmitting waveform, with which a space symbol is inserted in a transmitting data stream. SOLUTION: Concerning this waveform generating circuit, a ROM 14 for band limit filter stores only waveform data corresponding to the symbol data stream containing no space symbol. When the space symbol is required, waveform data corresponding to the symbol data stream located with the impulse response of one predetermined polarity at a position to locate the space symbol are selected out of the ROM for band limit filter, and the impulse response of an inverse polarity inverse to the impulse response of one determined polarity in these selected waveform data is outputted from a ROM 15 for waveform generation and added by an adder 16. Thus, the waveform data at the position of the space symbol are canceled and the space symbol can be located at that position.
