“…Manuscript As a means of the wavelength tuning for the polymer DFB lasers, thermooptic effect of the polymer materials is applicable to modify the effective index of the grating waveguide. However, the tunable range by the thermooptic effect is limited to several nanometers during the operation around room temperature [13]. Furthermore, the lasing wavelength, of course, is limited in the emission band of dye doped in the active layer.…”

We demonstrated a wavelength-switchable lasing operation in a single-chip polymer waveguide device. This device has a single active layer codoped with two organic dyes, Stilbene 420 and Rhodamine B, and is equipped with a distributed-feedback resonator by a single-pitched grating. Since there is no significant spectral overlap between the emission band of Stilbene 420 and the absorption band of Rhodamine B, both of these dyes could be simultaneously activated as the optical gain media in the active layer. Under the optical pumping, bistable blue and red lasing emissions were obtained, which were attributed to the third-order distributed-feedback oscillation for the Stilbene 420 emission and the second-order distributedfeedback oscillation for the Rhodamine B emission, respectively. These lasing modes could be easily switched by changing the pumping wavelength.

“…But the step-by-step movement is difficult in MEMS device, and thus the continuous wavelength tuning will not be achievable. As a means to perturb N eff , on the other hand, thermooptic (TO) effect for the material index of the plastic material is available [24], [25]. However the variation of λ B based on this mechanism is also limited to ∼0.5% in the room temperature range (e.g., 20-50°C).…”

A wavelength tunable plastic laser with asymmetric distributed Bragg reflectors (DBRs) is proposed. This device consists of a pair of long-period waveguide gratings and a polymeric active waveguide doped with an organic dye. Due to the difference in grating periods between the two DBRs, the lasing wavelength can be tuned in accordance with a Vernier effect of the resonance between the reflection wavelengths. The plastic laser device operated with this principle has promise as a compact and widely tunable light source because a large wavelength shift in a wide emission band of an organic luminescent material can be expected with a small variation in the effective index.Index Terms-Distributed Bragg reflector, plastic laser, wavelength tuning.
