M. Allovon et al., MONOLITHIC INTEGRATION ON INP OF A WANNIER-STARK MODULATOR WITH A STRAINED MQW DFB 1.55-MU-M LASER, IEEE photonics technology letters, 7(2), 1995, pp. 185-187
We present the technical approach and the preliminary device results o
n the first integration of a Wannier Stark (WS) electroabsorption (EA)
modulator with a DFB laser on InP. The WS modulator active layer cons
ists of a lattice matched InGaAs-InAIAs superlattice (SL) grown by sol
id source MBE. It is butt-coupled to a laser grown by AP-MOVPE whose a
ctive layer includes a strained InGaAsP-InGaAsP MQW stack. Device resu
lts cover static performances of integrated lasers and modulators, and
measurements of high frequency characteristics (small signal bandwidt
h and 10 Gb/s eye diagram).
