摘要：
A `big spot` semiconductor laser has a passive modal spot size transformer (2) formed integrally in tandem with the active region (1) of the laser. The passive transformer has a layer structure (5, 6) that supports a restricted set of modes and is designed such that, at the laser frequency, its length provides a phase slippage of .pi. between modes of adjacent order.
