Patent ID: 7004645

Claim:
A parallel wavelength division muitiplexing transmitter comprising: a first VCSEL die in a first group, said first VCSEL die comprising a first two dimensional single wavelength monolithic VCSEL array, said first two dimensionai single wavelength monolithic VCSEL array operable to emit light at a first wavelength; a second VCSEL die in said first group and proximate to said first VCSEL die, said second VCSEL die comprising a second two dimensional single wavelength monolithic VCSEL array, said second two dimensional single wavelength monolithic VCSEL array operable to emit light at a second wavelength; a third VCSEL die in said first group and proximate to said first VCSEL die, said third VCSEL die comprising a third two dimensional single wavelength monolithic VCSEL array operable to emit light at a third wavelength; a fourth VCSEL die in said first group and proximate to said first VCSEL die, said fourth VCSEL die comprising a fourth two dimensional single Wavelength monolithic VCSEL array operable to emit light at a fourth wavelength, such that said first, second, third and fourth wavelengths are distinct from one another; and a first, a second, a third and a fourth optical fiber are configured such that each one of said first, second, third and fourth optical fiber is optically coupled to said first, second, third and fourth two dimensional single wavelength monolithic VCSEL arrays.
