Novel fiber design for broadband long period gratings

Kakkar, Charu; Thyagarajan, K (2003)

We report a novel fiber design for obtaining long period gratings (LPGs) having a broad transmission spectrum. These gratings are based on guided to guided mode coupling in a staircase profile fiber. Numerical simulations ...
Novel fiber design for flat gain Raman amplification using single pump and dispersion compensation in S band

Thyagarajan, K; Kakkar, Charu (2004)

This paper reports on a novel fiber design that has an inherently flattened effective Raman gain spectrum. Simulations show that gain-flattened broad-band Raman amplification, using a single pump, can be achieved in any ...
