| 英文摘要 | A polarization independent optical amplifying apparatus of the present invention imparts a gain to a received input light signal. The optical amplifying apparatus includes a substrate and a plurality of semiconductor layers formed on the substrate. The semiconductor layers include at least one semiconductor layer having a TE-TM conversion function. A relation of L=2n pi [4 kappa 2-(gTE-gTM)2]1/2 is satisfied where L is a propagation length, n is a natural number, kappa is a coupling coefficient between TE mode light and TM mode light, gTE is a gain coefficient of the TE mode light and gTM is a gain coefficient of the TM mode light. The TE mode-TM mode conversion function may be caused by one of a magneto-optic effect, an electro-optic effect and an acousto-optic effect. |
