Analog measurements of long wavelength vertical-cavity lasers

We report the measurements of nonlinearity effects on analog transmission of long wavelength vertical-cavity surface-emitting lasers. The experiments involved measuring single-mode fiber-optic transmissions of microwave signals (100–1000 MHz) at 1.54 μm to characterize the dynamic range, intermodulation distortion and frequency response. Spur free dynamic ranges up to 69 dB were demonstrated.
