Visible dual wavelength light emitting diodes (LED's) have been successfully fabricated growing lattice matched In0.3Ga0.7P on GaAs0.6P0.4 commercial epitaxial substrate on GaAs. InGaP and GaAsP homojunction LED's have respective emission wavelength of 583 nm and 652 nm and cutoff frequencies of 8 MHz and 12 MHz.
