Kind Code:
A1
Abstract:
The present invention comprises: a core (102) formed on a lower clad layer (101) and composed of an amorphous undoped semiconductor (i-type); a p-type layer (103) and an n-type layer (104) which are disposed on the lower clad layer (101) with the core (102) interposed therebetween, and formed in contact with the core (102). The core (102) is formed thicker than the p-type layer (103) and the n-type layer (104). The p-type layer (103) and the n-type layer (104) are composed of a single crystal silicon.
