Latest Patents

Dapkus holds a patent for a "Method and apparatus for long wavelength semiconductor lasers." This invention features a W quantum well structure for the active region of semiconductor lasers, enabling long wavelength emission of photons. The energy band lineups in the disclosed heterostructures achieve emission at wavelengths of 1.3 µm or greater. The W quantum well structure and exemplary materials can be applied to any semiconductor laser, including a vertical cavity surface emitting laser (VCSEL). The active region consists of one or more sets of triad layers of GaAs N /GaAs Sb /GaAs N, which provide the W quantum well structure. The energy band of these materials offers a staggered band alignment, confining electrons and holes in adjacent layers. This design allows for optical emission at longer wavelengths than what is typically achievable from the energy gaps of the constituent materials alone.
