To demonstrate short-wavelength continuous laser operation at room temperature using specific quantum well heterostructures.
Used In1−y(AlxGa1−x)yP-In1−y(AlxGa1−x)yP quantum well heterostructures grown on GaAs substrates.
Employed metalorganic chemical vapor deposition for growth.
Investigated both continuous wave and pulsed laser operations.
Achieved continuous wave laser operation at a wavelength of 625 nm at 300 K.
Pulsed laser operation also achieved with a threshold current density of approximately 104 A/cm² at 625 nm.

Implication

Data demonstrate continuous laser operation at 625 nm in quantum well heterostructures, suggesting advancements in laser technology.

Abstract

Data are presented demonstrating very-short-wavelength (625 nm) room-temperature (300 K) continuous (cw) photopumped laser operation of In1−y(AlxGa1−x)yP-In1−y (AlxGa1−x)yP quantum well heterostructures grown lattice matched (y≊0.5) on a GaAs substrate via metalorganic chemical vapor deposition. In addition, 300 K pulsed laser operation (Jth∼104 A/cm2, 625 nm) of diodes fabricated from the same crystal is described.
