Abstract
In this work, we reported the 1.55 ㎛ ridge-type dual mode laser(R-DML) as a THz communication beating source. It have many advantages of cost effects, compactness and simplification of fabrication by introducing the ridge-type waveguides. We have demonstrated 10Gbps THz wireless communications with 10-3 BER (bit-error-rate) without digital signal processing.
