Patent number: 6584239Abstract: A doped slab region is described for use around a ridge waveguide, for controlling the refractive index of the waveguide material. Instead of simply diffusing dopant in from a surface of the slab region adjacent the waveguide, an area of the slab region is etched and dopant diffused in from a side face of the etched region. Thus, the dopant profile is established from a horizontal direction, allowing the profile to be controlled. A simple vertically uniform doping profile can thus be provided, leading to a vertically uniform current density, or an anisotropic wet etch can be applied after the initial etch to provide a profile which concentrates the current density at a selected height in the slab region.Type: GrantFiled: September 5, 2000Date of Patent: June 24, 2003Assignee: Bookham Technology plcInventors: Emma Jane Clarissa Dawnay, Arnold Peter Roscoe Harpin, Ian Edward Day
