Patent ID: 7280267

Claim:
An optoelectronic system comprising: an optical signal modulator, wherein said optical signal modulator is an electroabsorption modulator (EAM); an optical input guide and an optical output guide connected to said optical signal modulator, wherein said optical input guide and said optical output guide are a single optical guide; a reflective optical element in said optical signal modulator, said element disposed to reflect an input light beam incident through said optical input guide into an output light beam through said optical output guide; an electrical terminal in said optical signal modulator, said electrical terminal configured such that an electrical signal on said electrical terminal is operable to interact with said input light beam, wherein said input light beam is operable to interact to modulate said electrical signal; and an optical circulator in communication with said single optical guide, said circulator adapted to receive said input light beam along a first path, to pass said input light beam to said EAM, and to pass said output light beam along a second path different from said first path.
