N2  - We investigated theoretically a waveguided EAM (Electro-Absorption Modulator) based on ISBT (Intersubband Transitions) in an In(0.53)Ga(0.47)As/AIAs/AIAs(0.56)Sb(0.44) A-CDQWs (Asymmetric Coupled Double Quantum Wells) lattice-matched to InP at telecommunication wavelength (?=1.55 ?m) which offers ultrahigh-speed and moderate voltage swing. Likewise, the temperature dependency in the In(0.53)Ga(0.47)As/AIAs/AIAs(0.56)Sb(0.44) A-CDQWs was investigated at different temperatures from 300 K to 400 K and evidently the InP-based ISB (Intersubband) modulator offers better temperature stability (~ 0.05 nm/C) compared to the InP-based IB (Interband) modulator. The EAM investigated here is anticipated to have a RC-limited speed (f3dB) of. 300 GHz with insertion loss of 5.1 dB, 10 dB extinction ratio and 5.18 dB/V modulation efficiency at a peak-to-peak voltage of 2.0 V which can support a data rate of up to 600 Gbps and beyond.
