GLASS BASED ADVANCED MID INFRARED
PHOTONIC DEVICES
Advances in low loss high purity glasses were initially driven by fiber-optic
communications, and the related interest in developing low loss optical fibers
covering a variety of spectral regions, which in turn led to development of fibers
as rare earth and transition metal ion host media for numerous unique fiber
amplifier and attenuator applications. Much lower Rayleigh scattering losses
achievable at longer wavelengths spurred the development of low loss mid-
IR fibers leading to three dominant families of glass fibers, namely fluorides,
chalcogenides, and tellurites. Of these families of mid-IR fibers and glasses,
the fluoride glass fiber technology has emerged as the most mature because
of its unique combination of broad transparency, glass stability, and its “fiberiz-
ability” into low-loss single-mode fibers.
The “fiberizability” of glasses is not only significant for fiber lasers and ampli-
fiers, but is also a good measure of the glass stability, which is quite critical for
making high-Q microresonators with a low amount of light loss due to scatter-
ing from crystallites and surface roughness. More recent work has focused
largely on the development of high optical nonlinearity glasses for applications
ranging from Raman amplifiers and comb generators to continuum generation.
I will review device optimization issues related to glass based mid infrared
optoelectronic devices, notably mid infrared fiber lasers and fiber amplifiers,
nonlinear optic frequency convertors and comb generators, and microreso-
nators for sensors and mid-IR microlasers. The use of advanced fabrication
techniques for fabrication of mid-IR glass fibers and mid-IR microresonators,
including the use of specialized molds for pouring molten glass to cast such
microresonators will be discussed. Specific achievements – including the at-
tainment of >20 Watts of output power in mid-IR fiber lasers will be discussed,
along with the prospect of achieving narrow linewidth sub-megahertz opera-
tion of mid-IR fiber lasers spanning the entire mid-IR spectral range between
2-7 microns.
