Abstract

An optical frequency comb was generated from a single quantum dot laser diode (QD-LD) in the 1-mm waveband using an Sb-irradiated InGaAs/ GaAs QD active medium. A single-mode-selection technique and interference injection-seeding technique are proposed for selecting the optical mode of a QD optical frequency comb laser (QD-CML). In the 1-mm waveband, a wavelength-tunable single-mode light source and a multiplewavelength generator of a comb with 100-GHz spacing and ultrafine teeth are successfully demonstrated by applying the optical-mode-selection techniques to the QD-CML. Additionally, by applying the single-mode-selection technique to the QD-CML, a 10-Gbps clear eye opening for multiple-wavelengths in 1-μm waveband photonic transport over a 1.5-km-long holey fiber is obtained.
