Abstract:
A method of forming a multi-quantum well laser diode comprising the successive steps of:a) growing a buffer layer on a cleaned substrate; b) growing a lower confinement layer on the buffer layer; c) doping the lower confinement layer with a n-type dopant; d) growing an active layer by growing, in sequence, successive layers of GaInN/GaN; e) repeating step (d) until from about 5 to about 30 period GRINSCH structure is formed comprising a plurality of layers of GaxIN1âˆ’xN/GaN(0&lE;x&lE;1); f) growing an upper confinement layer on the active layer; g) doping the upper confinement layer with a p-type dopant; annealing and forming contacts on the upper and lower confinement layers.
