A compact cascaded tunable distributed feedback semiconductor laser is proposed and theoretically analyzed. Each laser section (LS) is formed by two adjacent grating sections (GSs) with slightly different Bragg wavelengths and a <inline-formula> <tex-math notation="LaTeX">$\pi $ </tex-math></inline-formula> phase shift in the joint between them. A step-wise… CONTINUE READING
