Characterization and simulation of long period gratings fabricated using electric discharge
Palai, P; Satyanarayan, M N; Das, Mini; Thyagarajan, K; Pal, B P (2001)We report the characterization and theoretical simulation of long period gratings fabricated using electric arc discharge in two different fibers namely, SMF-28 (Δ=0.0036) and DSF (Δ=0.009). We show that this technique can ... -
Erbium-doped dispersion-compensating fiber for simultaneous compensation of loss and dispersion
Palai, P; Thyagarajan, K; Pal, B P (1997)A scheme for simultaneous compensation of dispersion and loss is proposed. It should be realizable by doping an optical fiber having a high negative dispersion coefficient at 1.55 mm with erbium ions. Numerical calculations ... -
A novel design of a dispersion compensating fiber
Thyagarajan, K; Varshney, R K; Palai, P; Ghatak, A K; Goyal, I C (1996)We propose a novel dispersion compensating fiber design consisting of two highly asymmetric concentric cores. We show that the fundamental mode of the proposed fiber can have very large negative dispersion values [~-5100 ... -
Role of Bend on the Optimization of 980-nm-Pumped Erbium-Doped Fiber Amplifier
Palai, P; Thyagarajan, K; Roy, Anil K; Pal, B P (1995)We describe optimization performed numerically for a 980-nm-pumped erbium-doped fiber amplifier in the presence of bending, for both fully and fractionally doped cores.All calculations are carried out using three-level ... -
