“…However, coupling to and from the micro-toroid in an integrated manner remains a challenge which must be overcome. In terms of laser performance, high slope efficiencies, in excess of 20%, have been demonstrated in Er:Ti:LiNbO 3 [263] and Er-doped phosphate glass [120,202,264,265]. A slope efficiency of up to 46% using bi-directional pumping was reported in [41].…”

Erbium-doped fiber devices have been extraordinarily successful due to their broad optical gain around 1.5-1.6 μm. Er-doped fiber amplifiers enable efficient, stable amplification of high-speed, wavelength-division-multiplexed signals, thus continue to dominate as part of the backbone of longhaul telecommunications networks. At the same time, Er-doped fiber lasers see many applications in telecommunications as well as in biomedical and sensing environments. Over the last 20 years significant efforts have been made to bring these advantages to the chip level. Device integration decreases the overall size and cost and potentially allows for the combination of many functions on a single tiny chip. Besides technological issues connected to the shorter device lengths and correspondingly higher Er concentrations required for high gain, the choice of appropriate host material as well as many design issues come into play in such devices. In this contribution the important developments in the field of Er-doped integrated waveguide amplifiers and lasers are reviewed and current and future potential applications are explored. The vision of integrating such Er-doped gain devices with other, passive materials platforms, such as silicon photonics, is discussed.

“…Figure 8 shows an integrated DFB-DBR coupled cavity laser that has been produced following this fabrication approach for applications related to wavelength division multiplexing (WDM) and interferometric instrumentation [46]. It consists of a Ti:Fe:Er:LiNbO 3 section with a photorefractive Bragg grating, representing the DFB laser, and the Ti:Er:LiNbO 3 gain section with a broadband multi-layer dielectric mirror of high reflectivity attached on its endface.…”

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...

“…Depending on the technological conditions and on the device design this phenomenon can play a negative role (deterioration of the optical beams -intensity instability, self-focusing and transversal spreading -when the optical power exceeds some critical value [71,72], etc.) as well as a positive role (writing of stable phase gratings for distributed Bragg reflection resonators in LiNbO 3 waveguide lasers [79][80][81][82]). Therefore, the photorefraction needs a careful analysis and treatment in each specific case.…”
