Claim Text:
1. An optoelectronic device comprising: a substrate; a first vertical cavity surface emitting laser (VCSEL) disposed on the substrate having a first distributed Bragg reflector (DBR) disposed above the substrate, a first quantum well (QW) region disposed above the first DBR, a second DBR disposed above the first QW region, and a first reflector disposed above the second DBR opposite the substrate, the first reflector reflecting light produced by the first VCSEL back into the optoelectronic device; and a Mach-Zehnder modulator (MZM) horizontally integrated into the optoelectronic device beside the first VCSEL, wherein the MZM receives light produced by the first VCSEL and modulates the received light to produce a modulated optical signal, wherein the MZM has a second reflector disposed in or on the MZM that prevents the light received from the first VCSEL from passing through a top surface of the MZM, wherein the first and second reflectors are different portions of a single reflector.
