Compensation of nonlinear phase noise impairments through optical phase conjugation in long-haul transmission systems
Differential-quadrature phase-shift-keying (DQPSK) can, unlike on-off-keying (OOK), be impaired by nonlinear phase noise (NPN). It has been shown that optical phase conjugation (OPC) is an effective compensation scheme for NPN resulting from the ASE of EDFAs (ASE-NPN). In this paper we discuss the influence of NPN resulting from modulator imperfections (MI-NPN). We show that MI-NPN can be compe...
متن کاملMethod for auto-alignment of digital optical phase conjugation systems based on digital propagation.
Optical phase conjugation (OPC) has enabled many optical applications such as aberration correction and image transmission through fiber. In recent years, implementation of digital optical phase conjugation (DOPC) has opened up the possibility of its use in biomedical optics (e.g. deep-tissue optical focusing) due to its ability to provide greater-than-unity OPC reflectivity (the power ratio of...
متن کاملEqualization enhanced phase noise in Nyquist-spaced superchannel transmission systems using multi-channel digital back-propagation
Superchannel transmission spaced at the symbol rate, known as Nyquist spacing, has been demonstrated for effectively maximizing the optical communication channel capacity and spectral efficiency. However, the achievable capacity and reach of transmission systems using advanced modulation formats are affected by fibre nonlinearities and equalization enhanced phase noise (EEPN). Fibre nonlinearit...
متن کاملDigital optical phase conjugation of fluorescence in turbid tissue.
We demonstrate a method for phase conjugating fluorescence. Our method, called reference free digital optical phase conjugation, can conjugate extremely weak, incoherent optical signals. It was used to phase conjugate fluorescent light originating from a bead covered with 0.5 mm of light-scattering tissue. The phase conjugated beam refocuses onto the bead and causes a local increase of over two...
متن کاملOptical phase conjugation in third-order nonlinear photonic crystals
We predict that the efficiency of the optical phase conjugation generation can be enhanced by more than four orders of magnitude in a xs3d nonlinear superlattice, as compared with that in a homogeneous nonlinear medium of the same sample thickness and xs3d nonlinearity. Such an effective enhancement utilizes the localized properties of the fields inside the sample at the band-edge state, gap-so...
