Nanowire Laser Structure and Fabrication Method

A laser array comprising:

• a plurality of nanowire laser structures, each nanowire laser structure of said plurality of nanowire laser structures comprising
• an elongated support element extending from a substrate, said support element having a first diameter;
• and
• an elongated body element extending on and/or around said support element, said body element having a second diameter at least two times larger than said first diameter;
• wherein said body element is spaced apart from said substrate;
• and
• wherein said substrate of each nanowire laser structure is a common substrate of said plurality of nanowire laser structures.

A method for forming a nanowire laser structure, comprising:

• forming a first reflective layer on a substrate layer;
• forming a hole in said first reflective layer, said hole extending to said substrate layer;
• and
• growing a nanowire laser structure in said hole;
• wherein growing said nanowire laser structure comprises growing a support element in said hole through said first reflective layer at a first diameter, and extending said support element above said first reflective layer, and growing a body element around at least a portion of said support element that extends above said first reflective layer said body element having a second diameter at least two times larger than said first diameter.
