英文摘要 | PURPOSE:To ensure a chip in which wavelengths are different on the same chip in a stepwise manner by charging stepwise the thickness of an active layer in the same surface. CONSTITUTION:There are provided a semiconductor substrate 1, a diffraction grating 2, a lower cladding layer 3, an active layer 4, an upper cladding layer 5, (the layers 3-5 are of a double hetero structure), an insulating film 6, and electrodes 7, 8. The thickness of the active layer 4 is altered stepwise. Accordingly, the equivalent refractive index of the active layer is different among chips 9a-9e following a relationship indicated by a curved line in the figure. Hereby, the wavelength yielded by the chips 9a-9e is stepwise different following the change in the thickness. |
