We present a detailed analysis of the static tuning characteristics of three section tunable distributed Bragg reflector (DBR) laser. The analysis is based on the transfer matrix method (TMM), transmission line and scattering theory. The key feature of the analysis is the use of modified oscillation condition. With the exact oscillation condition, the static tuning characteristics such as threshold current, output power, oscillating wavelength are obtained and the effects of a discontinuity at the active-passive interface and also the manufacturing imperfections on the device characteristics are investigated
