Document Type and Number:
Japanese Patent JP2010034408
Kind Code:
A
Abstract:
To provide a light-emitting element capable of defining a horizontal optical confinement property without depending physical property values too much.
On a substrate 10, a lower clad layer 21, an active layer 22, an upper clad layer 23 and a contact layer 24 are formed in this order, and the upper part of the upper clad layer 23 and the contact layer 24 serve as a ridge waveguide 25.
