ABSTRACT:
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..sup.2 -(g.sub.TE -g.sub.TM).sup.2 ].sup.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, g.sub.TE is a gain coefficient of the TE mode light and g.sub.TM 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.
