Abstract
A novel concept to form a photo-detector integrated VCSELs using transverse-coupled-cavity (TCC) scheme is demonstrated. In our configuration one cavity suppressed by the reverse bias voltage at 1volt, while the other cavity used as a laser. Proton-implantation was used in order to prevent the current leakage. The formation aperture diameter of each cavity gives us multimode and quasi-single mode condition. Our preliminary results on L-I indicate the possibility of continues tracking of photocurrent in the range of 0.7- 10 mA, which is limited by the threshold and saturation level of the laser side cavity.
