Abstract
A novel gain control scheme of semiconductor optical amplifiers (SOAs)
using a heater-mounted SOA was investigated. In our proposal, a simple SOA
gain control using an on-chip heater provides a high saturation output power
over an entire gain control range of 10 dB. This scheme widely expands the
usable power range in output level control of a 10 Gbps NRZ-OOK signal,
compared to that of a conventional gain control operated by drive current.
As a result, the heater-mounted SOA exhibited a large input power dynamic
range (IPDR) of ${>}17$ dB up to the output power of ${+}8.0$ dBm in level control operation.
