We construct a high gain high output power 1310 nm hybrid fiber amplifier, which can be use in telecommunication. It is a compact design combining a semiconductor optical amplifier (SOA) and a discrete Raman amplifier. It is hard to construct such amplifier by either using a SOA or a discrete Raman fiber amplifier with compact design. The amplifier is designed for a 1310 nm small signal input providing...
We have demonstrated multiwavelength fiber laser (MWFL) based on bidirectional Lyot filter and semiconductor optical amplifier (SOA). The intensity dependent loss (IDL) mechanism is utilized to obtain a flat multiwavelength spectrum of 94 wavelength lines within 5 dB bandwidth. The extinction ratio (ER) is 9 dB, while the line spacing is narrow at 0.1 nm. No polarizer is used in the experimental structure,...
We propose and demonstrate, for the first time, service multicasting by all-optical routing of 1 Gb/s IR-UWB using XGM of SOA. This technique has potential applications for integrating IR-UWB with WDM PON and in-building networks.
This paper describes the development of a transmitter and receiver leveraging a combination of monolithic and hybrid integration for Datacenter applications to deliver 500Gbps over 2 km on a single mode fiber. The transmitter encompasses 12 electro-absorptive modulated lasers (EMLs) with wavelength channels from 1270 nm to 1380 nm on a 10 nm channel grid. The lasers are grouped in three (3) arrays...
In this paper, we propose the new architecture of the optical switching fabric which is based on the baseline switching network. Traditional baseline switching networks are composed of 2 ?? 2 (or d ?? d) switches. The new architecture considered in this paper is constructed from 2 ?? 2, 3 ?? 3, 2 ?? 3 and 3 ?? 2 switching elements. We show, that the proposed architecture requires less crosspoints...
In this paper, we will put in perspective the Raman amplification challenges for next generation networks and review the physical principles and theory associated to this amplification technique.
We demonstrate a novel approach in the implementation of a broadband optical network unit using a semiconductor optical amplifier-based optical loop mirror, both experimentally and via simulations for up to 50 km and 2.5 Gb/s.
We propose a serialized sensor network using a reflected SOA (RSOA) as a low-cost and wideband source. The RSOA is self-injection locked by the FBG sensors with different center wavelengths. By reading the wavelength shifts, the number of sensors up to 32 can be monitored with the side mode suppression ratio of >27 dB within 4 km.
We investigate and demonstrate for the first time the benefit of IM-DPSK signals over NRZ signal in wavelength conversion using Four Wave Mixing in Semiconductor Optical Amplifier. Using this method, we experimentally demonstrate the wavelength conversion at 10 Gb/s with distance of 450 Km (5 span of 90 Km) using Non Zero Dispersion Shifted Fiber (NZDSF) Single Mode Fiber (SMF). The result shows the...
In this paper we present the linearization of Impulse Radar Ultra Wideband (IR-UWB) transmission system over fiber. The radio frequency signal of IR-UWB is transmitted over 50 km of the single mode fiber (SMF) using external Mach Zehnder Modulator (MZM), amplified, linearized and detected by PIN diode photo receiver. For improving the linearity and suppressing the four wave mixing (FWM) caused by...
We propose a new architecture for regenerative all optical wavelength conversion. The conversion utilizes the induced chirp in SOA amplifier and sharp frequency response filter. 20,000 km transmission and cascadability are demonstrated in recirculating loop experiment.
Variable gain gain-clamped operation has been demonstrated across the EDFA operating window using a novel technique. Gain clamped levels have been monotonically varied by 14 dB. The gain flatness of the device is less than 4 dB
