Abstract :
In conclusion, a new single-mode cutoff mesa GaAs-AlGaAs rib waveguide has been designed and demonstrated. Using the principle of the cutoff slab waveguide, this waveguide provides singlemode performance regardless of any deep etches that might be used for electrical isolation between integrated electrooptic devices. Single mode operation is achievable with a wide range of rib widths and does not require demanding etch depth tolerances
