Using aqueous precursors, we report successfully fabricating thin-solid films of two nucleic acids, ribonucleic acid (RNA) and deoxyribonucleic acid (DNA). We investigated the potential of these films deposited on a fiber optic platform as all-fiber integrated saturable absorbers (SAs) for ultrafast nonlinear optics. RNA-SA performances were comparable to those of DNA-SA in terms of its nonlinear transmission, modulation depth, and saturation intensity. Upon insertion of these devices into an Erbium-doped fiber ring-laser cavity, both RNA and DNA SAs enabled efficient passive Q-switching operation. RNA-SA application further facilitated robust mode-locking and generated a transform-limited soliton pulse, exhibiting a pulse duration of 633 femtoseconds. A detailed analysis of these pulsed laser characteristics compared RNA and DNA fiber optic SAs with other nonlinear optic materials. The findings of this research establish the feasibility of utilizing RNA as a saturable absorber in ultrafast laser systems with an equal or higher potential as DNA, which presents novel possibilities for the nonlinear photonic applications of nucleic acid thin solid films.

“…Important advantages of using DNA biopolymer as a host for chromophores comprise the increased stability of embedded dyes, numerous possibilities for rendering it functional, versatility, and excellent thin film processability. The functionalization of DNA with different chromophores allows the tuning of the optical properties of the resulting DNA complexes for targeted photonic functionalities and applications, e.g., frequency conversion (third-harmonic generation) [ 7 , 8 , 9 ], light-induced spatial phase modulation [ 10 , 11 , 12 ], light-induced holographic diffraction gratings [ 13 ], and laser emission [ 14 ]. A review of the recent results obtained on DNA-based optoelectronics and photonics, along with some challenges and perspectives of DNA applications in these fields, is presented in [ 15 ].…”

Due to the increased application of lasers in different fields (industry, medicine, etc.), there is a growing need for new laser sources with good beam quality and variable emission wavelength. At the same time, for environmental reasons, the obtaining of novel eco-friendly active optical materials, such as those based on the deoxyribonucleic acid (DNA) biopolymer, with optimal light emission properties, is of high interest. The results obtained in this study of the temporal dependence of the transmittance and of the light emission in thin films of DNA–CTMA–Rhodamine 610 (at different Rhodamine concentrations) (DNA–CTMA–Rh610), when they are illuminated with continuous wave laser light at 532 nm (frequently used in the optical pumping of dye lasers), are presented and discussed. The transmittance results obtained for thin film samples are compared to those obtained for the DNA–CTMA–Rh610 solutions in butanol, from which the films have been made, and also with those obtained for Rh610 solutions in butanol with the same concentrations. The investigation was performed in order to assess the influence of the DNA-CTMA and of the green laser light at 532 nm wavelength on relevant chromophore properties such as light transmission and fluorescence emission. The results obtained revealed that the DNA–CTMA matrix has an active influence on the Rhodamine 610 emission, in the whole range of concentrations of the investigated samples.

“…The DNA-CTMA complex has high thermal stability up to a temperature of 100 °C [ 45 ], maintaining its double-stranded helical structure [ 53 ]. The DNA and DNA–surfactant complexes decompose in the 220–230 °C temperature range [ 40 , 53 , 54 , 55 ]. Their high thermal conductivity ensures a lower laser heating of materials based on them compared to other synthetic polymers (e.g., PMMA) with similar optical absorption [ 46 ].…”

“…Their high thermal conductivity ensures a lower laser heating of materials based on them compared to other synthetic polymers (e.g., PMMA) with similar optical absorption [ 46 ]. Another advantage of this new class of materials is the increased optical damage threshold after functionalization with natural dyes compared to synthetic polymers, [ 12 , 13 , 23 , 40 , 54 , 55 , 56 , 57 , 58 , 59 ], showing that the biopolymers are more resistant to high-energy laser pulses than some synthetic polymers like PC or PEG [ 40 , 55 ].…”

The high-power lasers have important implications for present and future light-based technologies; therefore, the protection measures against their high-intensity radiation are extremely important. Currently, a great deal of interest is directed towards the development of new nonlinear optical materials for passive optical limiters, which are used to protect the human eye and sensitive optical and optoelectronic devices from laser-induced damage. Biopolymers doped with natural dyes are emerging as a new class of optical materials with interesting photosensitive properties. In this paper, the optical limiting capability of deoxyribonucleic acid bio-polymer functionalized with Turmeric natural dye has been demonstrated for the first time, to the best of our knowledge. The experimental investigation of the optical limit has been done by the Intensity-scan method in the NIR spectral domain at the important telecommunication wavelength of 1550 nm, using ultrashort laser pulses (~120 fs). Several optical properties of this natural dye are presented and discussed. The values of the optical transmittance in the linear regime, the saturation intensity of the nonlinear transmittance curves, and the coefficient of the nonlinear absorption have been determined. The influence of the DNA biopolymer and natural dye concentration on the optical limiting properties of the investigated biomaterials is reported and discussed. The photostability and thermal stability of the investigated solutions have also been evaluated by monitoring the temporal decay of the normalized absorption spectra under illumination with UVA light and heating, respectively. Our results evidence the positive influence of the DNA, which embeds Turmeric natural dye, on the optical limiting functionality itself and on the photostability and thermal stability of this novel material. The performed study reveals the potential of the investigated novel biomaterial for applications in nonlinear photonics, in particular in optical limiting.
