“…However, annealing is less effective in recovering the lifetime of Er 3+ ions because the nonradiative relaxation in this case can be initiated even with a small number of OH-phonons [302]. Early work on laser sources using PE techniques focused on developing LiNbO 3 :MgO:Nd waveguides by pure PE [303], which were operated as cw [304], Q-switched [305,306], and mode locked [307] lasers. Laser oscillation was also demonstrated in channel waveguides produced in LiTaO 3 :Nd 3+ [301] bulk crystals and in Yb-indiffused LiNbO 3 planar slab waveguides (Fig.…”

Abstract:The tremendous interest in the field of waveguide lasers in the past two decades is largely attributed to the geometry of the gain medium, which provides the possibility to store optical energy on a very small dimension in the form of an optical mode. This allows for realization of sources with enhanced optical gain, low lasing threshold, and small footprint and opens up exciting possibilities in the area of integrated optics by facilitating their on-chip integration with different functionalities and highly compact photonic circuits. Moreover, this geometrical concept is compatible with high power diode pumping schemes as it provides exceptional thermal management, minimizing the impact of thermal loading on laser performance. The proliferation of techniques for fabrication and processing capable of producing high optical quality waveguides has greatly contributed to the growth of waveguide lasers from a topic of fundamental research to an area that encompasses a variety of practical applications. In this first part of the review on optically pumped waveguide lasers the properties that distinguish these sources from other classes of lasers will be discussed. Furthermore, the current state-of-the art in terms of fabrication tools used for producing waveguide lasers is reviewed from the aspects of the processes and the materials involved. 2 1.IntroductionOver the last two decades the field of solid-state planar waveguide lasers has experienced a steady growth, progressing from a laboratory curiosity to an area that demonstrates a broad spectrum of applications, from multiwavelength laser channel arrays for telecommunications to diode-pumped planar structures with multiwatt output powers for sensing and ranging applications. Waveguide lasers are by no means a new field and the first report on such a source dates back in 1961, when laser operation of a waveguide based on an active glass core rod embedded in a low refractive index cladding was demonstrated [1]. However research efforts in the years that followed this report focused primarily on the development of optically pumped laser sources based on high optical quality bulk dielectric laser media in the form of rods and slabs. The merits of the waveguide geometry and the associated optical confinement have been first highlighted in single mode glass optical fibers. Fibers have proven an enabling technology for realization of highly efficient amplifier and laser sources owing to their unrivalled low loss performance and ability to maintain a small spot size and hence high intensities over lengths that are orders of magnitude longer than would normally be allowed by diffraction, [2,3]. Er-doped fiber amplifiers (EDFAs) in particular have directly contributed to the enormous expansion of the optical communications networks that underpin today's internet infrastructure by allowing for signal regeneration and optical data transmission over long distances. The excellent performance of fiber lasers and amplifiers provided motivation and triggered a major techn...

“…In a more recent report transient laser emission was obtained from an Eu 3+ -complex-doped polymer by pumping with an ultraviolet N 2 pulsed laser [14]. The trivalent neodymium ion (Nd 3+ ) is arguably the most important active rare-earth ion for the demonstration of laser operation due to the large emission cross-section of its four-level transition ( [20], and Nd:silicate glass [21].…”

Abstract:A polymer host material, based on a cycloaliphatic diepoxy cured with a fluorinated dianhydride, has been developed. When activated with the rare-earth-iondoped complex, neodymium(thenoyltrifluoroacetone) 3 1,10-phenanthroline, the typical absorption and emission lines of the Nd 3+ ion are detected. Luminescence quenching, which usually occurs in polymers due to high-energy vibrations from O-H and C-H chemical bonds, is eliminated by the neutral 1,10-phenanthroline ligand and by applying fluorinated chelates to the complex, respectively, and absorption due to the polymer host occurs only in the wavelength range longer than 1100 nm. Optimization of the fabrication procedure of both, host material and optical structure, leads to steady-state laser emission from a channel waveguide near 1060 nm, providing up to 440 μW of output power from the waveguide structures developed. To the best of our knowledge, this result represents the first steadystate laser in a solid polymer host.

“…Especially, several studies have been reported on the rare earth (Nd, Er) ion doped LiNbO 3 [3,4]. This structure has advantages in that (1) a low-loss waveguide can easily be formed on the surface of LiNbO 3 by ion exchange and (2) modulation by the electro-optic (EO) effect by the second-order optical nonlinearity of LiNbO 3 crystal is possible so that functional waveguide lasers with Q-switch [6] and mode locking operation [7,8] or wavelength selection can be carried out. Several of these studies have been reported.…”
