TUNABLE LASER WITH A DISTRIBUTED BRAGG GRATING COMPRISING A BRAGG SECTION MADE OF STRAINED BULK MATERIAL
摘要
<p>The field of the invention is that of tunable laser devices with a distributed Bragg grating (DBR). The device according to the invention comprises a Bragg passive section consisting of a material whose optical index variations are controlled by an injection current, said material of the Bragg section being a strained bulk material with the strain applied to the bulk material being at least 0.1 %.</p>
