摘要： A semiconductor laser diode comprises a p-n junction. The p-n junction comprises a substrate, an n-type semiconductor layer, a p-type semiconductor layer, and a quantum well. The quantum well is disposed between the n-type semiconductor layer and the p-type semiconductor layer. The substrate is formed from a first material system, the n-type semiconductor layer is formed from a second material system, the p-type semiconductor layer is formed from a third material system, and the quantum well is formed from a fourth material system. The second material system is different from the third material system. The second material system and the third material system are selected such that there is an increase in the rate of recombinations of the electrons from the n-type semiconductor layer and the holes from the p-type semiconductor layer in the quantum well. This results in a lower turn-on voltage for the semiconductor laser diode.

摘要： An edge-emitting semiconductor laser (100) incorporating a narrow waveguide design is disclosed. The narrow waveguide (1700) expands the lateral mode size, creates a large modal spot size, and insures higher-order modes are beyond cutoff. Separate current confinement (150, 160) allows the current injection region to match the mode size. The resulting device exhibits single-mode operation with a large spot-size to high output powers.

摘要： The laser assembly (10) comprises a multimode laser (12) having at least one output and operating at a given wavelength. It also includes a double-clad optical fiber (20) having a free end (22) coupled to the output of the laser (12). The optical fiber (20) comprises a core (24) in registry with the output of the laser (12), a multimode inner cladding (26) surrounding the core (24), and an outer cladding (28) surrounding the inner cladding (26), the outer cladding (28) being provided to contain light in the inner cladding (26). A fiber Bragg grating (30) is written in the core (24) of the fiber (20) at a given distance from the free end (22) thereof. The Bragg grating (30) has a reflection spectrum within the gain spectrum of the laser (12). In use, it generates a sufficient feedback and stabilizes the laser (12) at the reflection spectrum of the Bragg grating (30). This provides a low cost laser assembly that is simple, suitable for volume manufacturing and small in size.
