“…Distributed Bragg reflector (DBR) lasers have several advantages such as dynamic single-mode lasing and high spectrum purity, and the lasing wavelength can be tuned by changing the refractive index in the DBR region. 1,2) Tunable DBR lasers utilizing refractive index changes caused by carrier injection [3][4][5][6] or thermal heating [7][8][9][10][11] have been developed.…”

A GaAsP quantum well tunable distributed Bragg reflector (DBR) laser with a thin-film heater above a DBR grating was designed and fabricated. As a result of the optimization of the DBR grating to obtain both high reflectivity and sharp wavelength selectivity, single-mode lasing with an output power of 54 mW and a side-mode suppression ratio of 43 dB was obtained. By forming the transparent thin-film heater at a distance of 0.1 µm above the DBR grating, the DBR grating was heated locally and efficiently, and a wide wavelength tuning range of 5.2 nm was achieved by heating with a heater power as low as 160 mW.

Wavelength tunable lasers are considered to be used for a wide range of applications such as local oscillator lasers for coherent communication, lasers for wavelength multiplexed communication, and improvement is expected by wavelength matching. So far, various wavelength tunable lasers have been reported. In particular, since diffraction grating integrated lasers such as DBR and DFB lasers can provide wavelength tuning operation by current injection, they have actively been researched and developed. This paper discusses the wavelength tuning principle, structures, and characteristics for these monolithic wavelength tunable lasers. The widest range of wavelength tuning, approximately 10 nm of tunable range, has been obtained by a three‐region DBR laser with a phase control region, but it has a complex structure and there are problems of low light output power and linewidth broadening associated with wavelength tuning. Although any DFB type tunable laser exhibits a small continuous tunable range of at most 2 to 3 nm compared to DBR type, it can provide a narrow linewidth and has an advantage of simple structure. Here, we show that these tuning ranges are theoretical limits, and further improvement in the wavelength tuning range requires the development of new technology.
