The use of a 35 GHz reflective electroabsorption modulator (REAM) monolithically integrated with a semiconductor optical amplifier (SOA) for indoor wideband analogue applications is demonstrated. Unlike REAMs, good performances over a wide range of input optical power and wavelength are observed, which mitigates the need for accurate control of the input signal, especially at remote sites where simplicity is strictly required. In addition, it provides amplification functions to compensate for the modulator insertion losses. The device exhibits an RF gain in excess of −22 dB and spurious‐free dynamic range of >103 dB Hz 4/5 . Implementing the rate‐adaptive discrete‐multitone modulation, 35 Gbit/s aggregate transmission speed is demonstrated for a short‐range wideband subcarrier multiplexed radio‐over‐fibre system.
