- Abstract
We investigate the bandwidth limitations and the analog modulation characteristics at microwave frequencies (0.1 to 10 GHz) of a low-capacitance oxide-confined 670-nm InGaAlP vertical-cavity surface-emitting laser (VCSEL). A maximum modulation bandwidth of 6.3 GHz, limited by thermal effects, is achieved. From measurements of distortion and noise, a spurious free dynamic range (SFDR) of 100 dB Hz2/3 is obtained at frequencies up to 2 GHz, rendering such VCSELs useful for transmission of analog signals. At higher frequencies, the SFDR drops due to the thermally limited resonance frequency. 2004 Society of Photo-Optical Instrumentation Engineers.
