Singlemode operation with an output power of up to 100 mW is reported for the first time for InGaAsP-InP DBR lasers. These devices exhibiting a record 17 nm tuning range, have been realised using a three-step MOVPE process. The output power variations under tuning are limited to ~1.5 dB, and the tuning range remains quasi-constant with output power
