Abstract

We proposed the vertical mode coupling structure (VMCS) for monolithic integration of optoelectronic devices. The electroabsorption duplexer (EAD) chip was fabricated by monolithically integrating both a waveguide photodiode (PD) and an electroabsorption modulator (EAM) in association with traveling wave electrodes. Using an EAD we presented a transceiver (TR_x) module for dual functions of both electrical-to-optical (E/O) and optical-to-electrical (O/E) conversions at 60GHz band. The responsivity and the extinction ration of the EAD were 0.72 A/W and 20 dB at -4 V_dc, respectively. The coupling loss between the optical fiber and the device facet was as small as 1.96 dB. The small signal 3 dB bandwidth of E/O and O/E response was 25 GHz and 8 GHz, respectively. We also investigated the issues of RF packaging in which the optoelectronic and electronic amplifier devices were co-packaged in a single housing.
