The super-continuum spectrum sliced WDM FSO system is evaluated at 2.5 Gbps data rate up to link distance of 5 Km.
The development of super continuum sources is driven by the requirements of a wide range of emerging applications.
The VIS IR white light super continuum (500 1000 nm) which was use to probe the excited region was generated by focusing the 800 nm pulses on a 1-mm sapphire plate.
Similarly a super continuum in the UV region of the spectrum was also generated with 400 nm pulses.
A series of spectral filters are used to shape the light emitting from a super continuum light source (Fianium, Eugene, OR) that is then collimated onto the sample and reference mirror using L2 and L3/L4 as illustrated in Fig. 1.
Similarly a super continuum light in the UV region of the spectrum was also generated using 400 nm pulses.
A small part of the fundamental 796 nm pulses were used to generate VIS-IR super continuum light by focusing the beam on a 1 mm thick sapphire plate.
A small part of the fundamental energy was also used to generate a super continuum white light by focusing the beam on a sapphire plate.
A nonlinear crystal was used to generate 400 nm for the purpose of exciting the NWs, whereas part of the fundamental was used to generate a super continuum light for probing different energy states.
The Si-NC sample was probed with a super continuum white light with photon energies ranging between 2.75 and 1.26 eV.
Non-linear crystals were used to generate 266/400 nm for the purpose of exciting the Sn-doped In2O3 NWs whereas part of the fundamental pulse was used to generate a super continuum light for probing different energy states.
