Distribution of timing and frequency signals in a fast-changing world requires unprecedented levels of stability for characterization. Transfer of frequency references over long distance without introducing any additional instability is of urgent con

The telecommunication industry has implemented fibre deployment guidelines that reliably safeguard cable health during installation in the field. While installed fibre cables remain buried in the field, temperature and moisture in the locality subjec

We experimentally characterized and optimized the performance of a vertical cavity surface-emitting laser (VCSEL) in a communication link. VCSEL at 1550nm transmission windows was chosen for data rate of 10 G bps for metro networks due to its wavelen

We report on simultaneous sum-frequency mixing and doubling of C-band and ∼ 980 n m laser sources using a single segmented periodically poled lithium niobate (PPLN) crystal in a single-pass configuration. Our theoretical analysis on the spectral ou

The fast growth of data traffic in access networks calls for high speed and low-cost optical links. To extend reach for users in metro areas requires optical amplification of the signal carrying data. In this paper we experimentally demonstrate a cos

Fiber optic sensors for industrial, consumer, medical and military applications have been reported. Their working principle is majorly based on non-linear optics. For the first time to our knowledge, we propose a cost-effective real time monitoring p

Vertical cavity surface emitting lasers (VCSELs) are now major optical sources in optical communication and technology. The VCSEL-based transmission systems satisfy the next generation optical fibre access networks requirements such as low output pow

We investigate both experimentally and by simulation the Noise Figure (NF) and pump reflection power of a Distributed Fibre Raman Amplifier (DFRA) as a function of pump power and fibre length, at different pump configurations. A DFRA of lengths 25 km

We experimentally investigate the effects of increase of the differential group delay (DGD) on Raman gain and gain value. It was found that the increase of DGD values lead to the formation and the increase in the number of ripples at the expense of g
