Abstract :
We designed a 10 Gb/s driver IC for direct modulation of VCSEL (vertical-cavity surface-emitting laser) diodes, using InGaP/GaAs heterojunction bipolar transistor technology with a cut-off frequency of 45 GHz and an emitter area of 6 μm2. The fiber launched optical output signal of the VCSEL driven by the fabricated driver IC exhibits rise/fall times of 54.3/68.6 psec and a controllable extinction ratio at a 3.3 V supply voltage with 250 mVpp input data sequence. The driver IC consumes a small power of 65 mW as well.
