Claim 13:
14. A semiconductor light emitting element comprising:
a lower electrode;
a substrate on a top surface of the lower electrode;
a first clad layer on a top surface of the substrate;
an active layer on a top surface of the first clad layer;
a left first optical loss layer on a left portion of a top surface of the active layer;
a second clad layer on a center portion of the top surface of the active layer;
a right first optical loss layer on a right portion of the top surface of the active layer;
a cap layer on a top surface of the second clad layer;
an insulating film contacting:
(i) a first portion of the top surface of the active layer located leftward of the left first optical loss layer,
(ii) a left side, a top, and a right side of the left first optical loss layer,
(iii) a second portion of the top surface of the active layer located between the left first optical loss layer and the second clad layer,
(iv) a left side of the second clad layer,
(v) a left side of the cap layer,
(vi) a left side of a top surface of the cap layer,
(vii) a right side of the top surface of the cap layer, such that a vertical contact hole in the insulating film extends upwards from a central portion of the top surface of the cap layer,
(viii) a right side of cap layer,
(ix) a right side of the second clad layer,
(x) a third portion of the top surface of the active layer located between the second clad layer and the right first optical loss layer,
(xi) a left side, top, and right side of the right first optical loss layer, and
(xii) a fourth portion of the top surface of the active layer located rightward of the right first optical loss layer; and
an upper electrode covering a top surface of the insulating film, penetrating the contact hole, and contacting the central portion of the top surface of the cap layer.
