Abstract

We report CW single-wavelength emission at RT from non-grating active multi-mode interferometer laser diodes (MMI LDs) by using an asymmetric configuration. Fabricated devices showed side-mode suppression ratio (SMSR) of 31dB (λ=1.56µm). We also present the modulation characteristics of this novel device at 1.25Gbps for a 2⁷-1 pseudorandom binary sequence.
