Title: Experimental Study of a Hybrid Small-Signal Parameter Modeling and Extraction Method for a Micro-Optoelectronic Device


Abstract: 

In the device performance variation and control for micro-devices, accurate models are critical for predicting DC behaviors as well as high-frequency behaviors. Thus, acquiring the characteristics of an optoelectronic device is essential for estimating its application to high-throughput control systems. In particular, we present an experimental and analytical investigation for extracting the parameters and intrinsic properties of an optoelectronic micro-device. Our study utilizes a near-infrared, InGaAsP buried hetero-structure, multi-quantum well distributed-feedback laser. We utilize a modified frequency response model and the conventional method of subtracting frequency responses in two different bias currents above the laser threshold current to attain the resonance frequency and damping factor using a simple four-parameter curve fitting procedure. With this method, we were able to acquire the intrinsic properties of the laser and its frequency response. In addition, the series resistance, which is drawn directly from a modified current-voltage (I-V) curve, can explicitly reflect the operation of the laser below and above threshold current. The parasitic capacitance was found by comparing the measured and extracted intrinsic frequency responses. Our extracted results agree well with previously published results.
