“…The lasing wavelength was varied in accordance with a Vernier effect of the resonant wavelength, which was sensitive to the variation in the effective index. Generally the organic materials have wide gain bands in contrast to the inorganic materials [17], [35], [36]. Therefore, the solidstate organic laser with the asymmetric DBRs has promise as a compact and widely tunable laser light source because a large wavelength shift can be expected with a very small perturbation.…”

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.

“…To achieve the wide tuning of the lasing wavelength, combination use of plural dyes with different emission bands is necessary. In this case, however, the gain material must be replaced in order to change the emission band [14].…”

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.

“…It has been reported in the literature that tuning ability usually does not exceed several dozens of nanometers. 5,6 The key point to overcome this drawback is the usage of a mixture of organic dyes, emitting light in different spectral regions. Enlargement of the lasing spectral range may be accomplished by employing two general concepts.…”

The spectral tuning range of dye lasers is closely associated with the gain profile provided by the utilized luminescent compound. Here, we present the results of studies aimed at broadening the wavelength tuning range in distributed feedback (DFB) lasers, made up of polymeric layers doped with a mixture of two complementary dyes. We have used the 3-(2,2-dicyanoethenyl)-1-phenyl-4,5-dihydro-1H-pyrazole (DCNP) luminescent dye, showing stimulated emission in its crystalline form, and the Rhodamine 700 (Rh700) laser dye, which is red-shifted in luminescence relative to DCNP, both doped into a poly(methyl methacrylate) (PMMA) host matrix. We have investigated the relationships between the additives' relative weight to weight ratios and their ability to exhibit a nonradiative energy transfer process that is inherent with a luminescence quenching of the shorter wavelength emitter, the so-called donor. This in turn directly reflects the efficiency of simultaneous utilization of both dyes' emission bands for lasing. By the proper engineering of the gain material composition, it was possible to broaden the DFB lasing tuning spectral range up to 125 nm, which is twice as much compared to the DCNP/PMMA material, i.e. without addition of Rh700. Finally, the presented results have shown that additional random feedback, which is detrimental to the DFB lasing, originating from the presence of DCNP crystals within the polymeric bulk, can be effectively suppressed by the superposition of a temporary DFB resonator.
