Liu, Y and Davies, AR and Ingham, JD and Penty, RV and White, IH (2005) Uncooled DBR laser directly modulated at 3.125 Gb/s as athermal transmitter for low-cost WDM systems. IEEE Photonics Technology Letters, 17. pp. 2026-2028. ISSN 1041-1135Full text not available from this repository.
An uncooled three-section tunable distributed Bragg reflector laser is demonstrated as an athermal transmitter for low-cost uncooled wavelength-division-multiplexing (WDM) systems with tight channel spacing. A ±0.02-nm thermal wavelength drift is achieved under continuous-wave operation up to 70 °C. Dynamic sidemode suppression ratio of greater than 35 dB is consistently obtained under 3.125-Gb/s direct modulation over a 20 °C-70 °C temperature range, with wavelength variation of as low as ±0.2 nm. This indicates that more than an order of magnitude reduction in coarse WDM channel spacing is possible using this source. © 2005 IEEE.
