Abstract
In optical storage systems, the demand for fast optoelectronic integrated circuit (OEIC) is dramatically increasing especially in the blue spectral range (λ=405nm). A new OEIC for the blue spectral range, which is integrated monolithically with the 0.6μm BiCMOS circuit, is presented in this paper. Proposed OEIC is optimized with respect to bandwidth, sensitivity, and noise in order to achieve high S/N ratio. N+ Finger/Nepi/PBL/Psub photodiodeachieves a responsivity of 0.31A/W at blue range corresponding to a quantumefficiency η of 95% [with Optimized ARC for blue range], afrequency response of 450MHz and a rising/falling time of 0.578ns. 3dB frequency response of 204MHz and noise of -91.8dBm [1~120MHz @ RBW=30 KHz] are obtained for the fast channel amplifier. Jitter value of 5.1% is achieved compared to the commercial OEIC of 5.4%.
