It will be revealed that a myth of deploying low bit-rate uplink fiber-to-the-home (FTTH)
services while providing a high bit-rate downlink is wrong. Therefore, for the future …

A novel ring-resonator-based integrated photonic chip with ultrafine frequency resolution,
providing programmable, stable, and accurate optical-phase control is demonstrated. The …

The performance of the phase-shifted superstructured fiber Bragg grating (SSFBG) for
optical code (OC) recognition was investigated with different reflectivity as well as input …

Given K simultaneously active users, an Optical CDMA (OCDMA) receiver needs to
discriminate among K codes. Since the number of available codes C is always C Gt K at any …

We propose and experimentally validate a novel method for transmitting several OCDMA
channels in the unused bandwidth of a single WDM channel, thus allowing the OCDMA and …

1 The most common metric for evaluating the performance of an optical communications
system is the symbol error probability (SEP) versus the received optical power. In circuit-like …

An important functionality in many optical systems is to manipulate the spectral content of
light. Diffractive optics has been used widely for this purpose. Typically, in such systems a …

This thesis reports some investigations on different aspects that characterize the next
generation optical access networks (NGAN) and that contribute in improving the …

Micro-electro-mechanical systems (MEMS) technology originated from the integrated circuits
(IC) industry, and has gradually evolved into a wide range of technologies across multiple …
