Latest Patents

Cherng's latest patents include a nitride-based semiconductor laser diode device featuring a bar mask. This innovative device comprises a selective growth mask with a grating structure. The design includes island-like stacked epitaxial layers, which consist of a P-type cladding layer formed from the selective growth mask upon the active layer of the semiconductor laser structure. This proposed structure effectively reduces strain caused by deformation due to the isolated structure. Consequently, it allows for an increase in the thickness of the cladding layer and/or an increase in composition difference without the risk of cracks in the island-like stacked epitaxial layers. Additionally, the optical confinement of the device can be significantly improved.
