摘要： The present invention can provide an npin-type optical modulator that has a high withstand voltage and is easily fabricated. A semiconductor optical amplifier (10) according to an embodiment of the present invention is an npin-type semiconductor optical modulator in which layers are sequentially stacked, with a cathode layer (12-1) arranged on the substrate side, including at least a first n-type cladding layer (13-1), a p-type cladding layer (14), a core layer (17) and a second n-type cladding layer (13-2). In this semiconductor optical modulator, the p-type cladding layer (14) is electrically connected to an electrode (18-1) of the cathode layer. Accordingly, the accumulation of holes in the p-type cladding layer associated with light absorption in the npin-type optical modulator can be absorbed in the electrode on the negative side. This npin-type semiconductor optical modulator can be comparatively easily fabricated using conventional semiconductor manufacturing techniques by adopting a mesa type waveguide structure.

摘要： The present invention relates to a semiconductor optoelectronic waveguide having a nin-type hetero structure which is able to stably operate an optical modulator. On the upper and lower surfaces of the core layer determined for the structure so that electro-optical effects are effectively exerted at an operating light wavelength and are provided with intermediate clad layers having a band gap which is greater than that of the core layer 11. Respectively on the upper and the lower surface of the intermediate clad layer are provided the clad layers having the band gap which is greater than those of the intermediate clad layers. On the upper surface of the clad layer are sequentially laminated a p-type layer and an n-type layer. In the applied voltage range used under an operating state, a whole region of the p-type layer and a part or a whole region of the n-type layer are depleted.

摘要： There is provided a semiconductor optical modulator capable of performing a stable operation and having an excellent voltage-current characteristic to an electric field while exhibiting the characteristic of a semiconductor optical modulator with an n-i-n structure. The semiconductor optical modulator includes a waveguide structure that is formed by sequentially growing an n-type InP clad layer (11), a semiconductor core layer (13) having an electro-optic effect, a p-InAlAs layer (15), and an n-type InP clad layer (16).
