Web摘要： Introducing a 1% compressive strained multiquantum-well (MQW) active layer into a corrugation-pitch-modulated distributed feedback (CPM-DFB) laser reduces the linewidth floor (residual linewidth for extrapolated infinite output power) to 2 kHz and results in a linewidth-power product of 140 kHz. mW. Strained MQW CPM-DFB lasers produced a …

WebA time domain model is used to study the large signal dynamics of general Bragg-detuned cavities. Such structures, in which the grating pitch is spatially nonuniform so that a distributed phase shift is produced along the cavity, are often called corrugation-pitch-modulated distributed feedback lasers (CPM-DFB). WebNarrow spectral linewidth lasers are necessary for coherent transmission systems, and linewidth less than 100 kHz have been achieved by a long-cavity corrugation-pitch- modulated distributed feedback (CPM-DFB) laser with a lattice-matched multiquantum well (MQW) active layer [1], a long-cavity distributed Bragg reflector (DBR) laser with a …
