									Aerosol Delivery System AES-02
APPLICATIONS:
Aerosol delivery system AES-02 is an accessory for fabrication of optical fiber preforms, where special
dopants and precursors are delivered into deposition zone by aerosol technology. This method permits
either aerosol or direct particle deposition techniques (in-situ deposition) to be used in fabrication of highly
doped        amplifier       fibers
(EDFAs) or dual clad (laser)
fibers.      Using       nebulizer,
dissolved reagents are sent
into      deposition     zone    in
substrate tube in the form of
liquid, finely dispersed into
very small droplets.


DESCRIPTION:
AES-02 unit is an add-on device for standard MCVD preform making system (but can be used with OVD
and PCVD devices as well), which permits use of MCVD preform lathe for fabrication of standard preforms

when aerosol process is not used. It can be (on customer’ request) integrated with deposition system
control software and process computer.

PRECURSORS & SOLVENTS:
AES-02 aerosol system permits use of reagent solutions containing glass forming materials (i.e. TEOS or
even silica particles), rare earth ion precursors (chelates, acetates), aluminum, germanium or phosphorous
containing precursors, dissolved in water, alcohol or cyclic organic solvents. The choice of precursor

materials is wide and permits research and development engineer to vary glass compositions with precision
and to develop new materials or characteristics
Aerosol process is suited for in-situ deposition of
highly doped glass layers in fabrication of rare earth
doped amplifier and dual clad fibers. Doping by
transition elements and metal ions is also possible.
By its versatility and wide choice of reagents, it
provides development and research engineers with
exciting possibilities to design new and improved
silica glass materials and products.
