Although χ^(2) nonlinear optical processes, such as difference frequency generation (DFG),
are often used in conjunction with fiber lasers for wavelength conversion and photon-pair …

Second harmonic generation (SHG) in glass optical fibers calls for creating a second order
susceptibility in the fiber glass and for achieving phase matching between the pump and the …

Electric-field-induced second harmonic generation (EFISH) as a third order nonlinear
process is of high practical interest for the realization of functional nonlinear structures …

Second order nonlinear optical properties and structural rearrangements in GeO 2 single
bond Na 2 Osingle bondNb 2 O 5 glasses were achieved by thermal poling. The effects of …

Whispering gallery mode (WGM) resonances in radially, thermally poled glass hetero-fibers,
are investigated for the first time. Upon radially oriented thermal poling, both TE and TM …

There is some incertitude on the creation of the term “photonics” and some ambiguity about
its frontiers (and differences with respect to optoelectronics and electro-optics). Many …
