| 英文摘要 | PURPOSE:To enable a compact and stable ultrashort pulse generator in high frequency exceeding 10 GHz to be manufactured by a method wherein a resonator structure is formed of a branched optical waveguide to be provided with a region for controlling optical phase and/or absorption loss. CONSTITUTION:An optical waveguide 15 comprising InGaAs as an outer resonator is monolithically formed of III-V compound semiconductor material similar to that of a semiconductor laser 1 on an InP substrate 14 with other elements comprising InP. This outer resonator 15 is fitted with electrodes 4, 5 to be impressed with electric field or to flow current while a reflecting end of this outer resonator 15 is fitted with a reflecting coating 9. The phase in the outer resonator 15, i.e., the refractive index and absorption loss is controlled by changing the refractive index and/or absorption loss of material by means of impressing electric field or flowing current through the electrodes 4, 5. Through these procedures, mode-synchronized ultrashort optical pulse beams in repeating frequency beyond 10 GHz can be emitted easily and stably only by means of impressing the electrodes of outer resonator with outer electric control signals. |
