Abstract :
A new distributed Bragg reflector (DBR) laser with continuously and arbitrarily chirped gratings is theoretically analysed. The chirped gratings are defined by bent waveguides on homogeneous grating fields. The influence of the chirped gratings on tunability of multielectrode DBR lasers is presented via the study of different bending functions. It is theoretically shown that the tunability of these components can be improved using the appropriate chirping function
