| Abstract(in English) | We have developed an L-band tunable distributed feedback laser array (TLA) with a new design to reduce the spectral linewidth. Narrow linewidth of <580kHz is obtained in entire tuning range (～40nm) with a high fiber output power of 20mW Furthermore, we investigated the causes of linewidth variation. We found that a TLA with a longer cavity is more tolerant to external feedback, which reduces the variation in linewidth. |
