  • Semiconductor laser
    Patent number: 11245248
    Abstract: A semiconductor laser includes a semiconductor layer including end faces and at least one of the end faces is configured as a light emission end face. The semiconductor layer includes a waveguide and a light window structure region. The waveguide has a first width and is extended between the end faces. The light window structure region includes an opening having a second width greater than the first width arranged along the waveguide and is formed continuously or intermittently from one to another of the end faces.
    Type: Grant

  • Multiwavelength laser diode
    Publication number: 20070001578
    Abstract: Rear end face films of a first device portion and a second device portion have a first reflective film in which one or a plurality of sets of a first rear end face film with a refractive index of n1 and a second rear end face film with a refractive index of n2 (?n1) are layered on the rear end face; and a second reflective film in which one or a plurality of sets of a third rear end face film with a refractive index of n3 (?n1) and a fourth rear end face film with a refractive index of n4 (?n1) are layered on the first reflective film.
