Abstract :
A 1 W record singlemode fibre coupled output power using 1460 nm InGaAsP/InP non-tapered buried ridge lasers has been demonstrated. The impact of the bandgap of the passive quaternary waveguide on internal loss was investigated. Optimised design allows internal losses as low as 3.3 cm-1, external efficiency of 0.46 W/A for a 3 mm-long laser and symmetrical (12°×12°) far-field pattern.
