| Abstract: | Effect of non-ideal response of a 90° hybrid in optical Costas loops has been examined. Even a very slight phase deviation ψ, from the ideal hybrid phase shift of 90° leads to increased power penalties and receiver sensitivities. Choice of the optimum power splitting ratio leading to a minimum BER, for a fixed laser linewidth, also increases. The greater the magnitude of the phase deviation, the more the system performance degradation. The nature of these variations does not depend significantly on the number of in-line optical amplifiers. |
