“…One of the core components in any high-performance balanced coherent receiver is the balanced photodetector. As explained in [2], the balanced photodetector must possess superior RF bandwidth matching in order to insure the required common-mode rejection ratio (CMRR) for high-sensitivity optical links.

“…The maximum optical peak current is 20 mA. The common-mode rejection ratio (CMRR) is better than 35 dB over the whole detector bandwidth [2]. For the 10 Gb/s set-up a balanced photodetector with a bandwidth of 35 GHz was used.…”

We report -31 dBm receiver sensitivity for heterodyne detection of 10 Gb/s OOK without using an optical pre-amplifier. These are the highest receiver sensitivities for unpreamplified heterodyne 10 Gb/s detection. We also show the development of a coherent heterodyne balanced fiber optic receiver. The receiver incorporates a DFB or a solid state laser local oscillator, balanced PIN photodiodes, RF post amplifier, automatic frequency control (AFC), phase locked loop (PLL), polarization control, and precision power supplies in a small instrument case. We will show shot noise limited detection of amplitude modulated signals, cancellation of laser RIN noise, performance improvement using balanced detection at 2.5 and 10 Gb/s, and IF linewidth reduction.

“…Esto permite que tras foto-detectar y sumar ambas señales moduladas, se consiga aumentar la relación IMD3, debido a que las contribuciones por distorsión armónica son menores. Por último, la foto-detección diferencial permite reducir el ruido RIN del sistema en el que se aplica [Jos05], por ejemplo, para un láser de -135 dB/Hz de ruido intrínseco relativo (RIN, Relative Intensive Noise) con P out de 5 dBm, se obtienen mejoras de 20 dB en SNR. Esta mejora de SNR permite conseguir mayores valores de SFDR que con un solo fotodiodo, lo cual, unido a la mejora introducida con el esquema linealizado, aumenta significativamente el margen dinámico del sistema.…”

IVPersonal Area Network). L'objectiu d'aquest estudi és obtenir màrges de seguretat per a garantir la interoperatibilitat d'ambdues tecnologies ràdio, els quals es poden aplicar en el futur desenvolupament de tècniques avançades de mitigació de la interferència com detecció i exclusió (DAA, Detect-and-Avoid), dins de futures aplicacions com les anomenades cognitive radio.Després, s'estudia la coexistència de MB-OFDM UWB i WiMAX IEEE 802.16e en xarxes òptiques d'accés basades en sistemes RoF. S'avaluen dos escenaris experimentals: en el primer, s'avalua un sistema RoF amb fibra multimode, i el segon, un sistema RoF amb fibra monomode. Els resultats permeten obtenir màrges de seguretat i abast màxim per al desplegament de sistemes RoF segons els tipus de fibra. Al mateix temps, es demostra i avalua experimentalment una nova tècnica de multiplexació per divisió en polarització de la transmissió òptica, per a millorar la coexistència en sistemes RoF.Finalment, aquesta Tesi Doctoral presenta l'estudi del modulador electro-òptic Mach-Zehnder, com a peça clau que limita el marge dinàmic de les transmissions als sistemes RoF. Al mateix temps, es proposa i avalua experimentalment una tècnica òptica de linealització del modulador Mach-Zehnder que millora el marge dinàmic del sistema RoF. V AbstractCurrent network and telecommunication systems are required to provide higher data rates in access networks to an increasing number of users. This fact is mainly due to the increase in the Internet traffic data, which is related with the higher demand of online videogames and software, the increased complexity in the content of web pages, the joint distribution of audio-visual and added-value online content, and the introduction of high-definition services and contents such as video on demand, as a result of a society increasingly more interconnected. In order to satisfy these higher data rates requirements, new techniques for the joint distribution of several wireless communication systems are proposed in this Thesis. The aim of these techniques is to facilitate the deployment of an integrated access network at the customer premises, enabling the integration of optical transmission over an optical access network and radio-frequency transmission in the same infrastructure.Two main wireless communication systems are considered in this Thesis, WiMAX (Worldwide Interoperability for Microwave Access) and UWB (Ultra-Wide Band) according to WiMedia Alliance recommendation. Comparing the bit rate and expected range, WiMAX and UWB are complementary radio technologies expected to coexist in a near future in integrated access networks. The optical access network considered in this Thesis can be regarded as a FTTH network (Fibre-to-the-Home). The wireless signals are natively transmitted over optical network, that is, without frequency upconversion and remodulation stages, over one or several optical carriers. This technology, which is known as Radio-over-Fibre (RoF), is well suited for integrated access networks.First, the requirements for...
