Design of optical matched filters by Pierre A Humblet( Book )

4 editions published in 1991 in English and held by 5 WorldCat member libraries worldwide

This paper studies the design and the performance of receivers using optical matched filters and direct detection, when the basic pulse shape consists a rectangular pulse of monochromatic light. The modulation format can be ASK, FSK or DPSK. Such receivers are useful when amplifier noise is the main source of uncertainty as they optimally reject additive white Gaussian noise. The performances of ASK and FSK receivers are reported, taking into account shot noise and the effects of post detection filtering

Crosstalk in direct-detection optical fiber FDMA networks by Walid M Hamdy( Book )

3 editions published in 1991 in English and held by 3 WorldCat member libraries worldwide

Direct-detection (DD) optical fiber frequency division multiple access (FDMA) is a simple and practical alternative to optical heterodyne FDMA. Previous works on estimating the performance of DD optical FDMA networks have usually focused only on the (linear) crosstalk degradation, typically relying on simplifying approximations such as the dominance of the adjacent channel interference [1], [4]. Other sources of performance degradation such as signal loss due to optical (predetection) and electrical (postdetection) filtering, intersymbol interference (ISI) due to the optical filtering, and channel beats (or nonlinear crosstalk) are usually ignored. This paper presents a more precise analysis that takes into account the effect of optical and electrical filtering, ISI, and linear crosstalk [3]. The model used here is valid for arbitrary optical filter transfer functions and received pulse shapes. We consider in this paper only On-Off-Keyed (OOK) modulation; extending the analysis to Frequency- Shift-Keyed (FSK) modulation is straightforward, but is not discussed here

Wavelength routing for all-optical networks by Richard A Barry( Book )

2 editions published in 1994 in English and held by 3 WorldCat member libraries worldwide

Abstract: "We consider passive all-optical networks using wavelength division multiplexing and wavelength routing, i.e. the path of a signal is determined by the wavelength of the signal and the signal origin. We present upper and lower bounds on the required number of wavelengths to achieve a given blocking probability. Specifically we show that between [formula] and O[square root of pM] wavelengths are required to support pM active session requests in a network with M users and blocking probability P[subscript b]. The lower bound holds for all networks with passive wavelength routing and fixed wavelength changing devices. The upper bound is a passive construction without wavelength changers."

Envelope detection of orthogonal signals with phase noise by Murat Y Azizoğlu( Book )

2 editions published in 1990 in English and held by 2 WorldCat member libraries worldwide

We analyze the performance of receivers which use envelope detection at IF to detect optical signals with orthogonal modulation formats. We obtain exact closed- form expressions for the error probability conditioned on the normalized envelope. The only information necessary for obtaining the unconditional error probability is the set of tilted moments of the envelope. We then provide an approximation to this envelope which is not only accurate to the first order in phase noise strength, but also has the same range as the actual random envelope. We use this approximation to obtain the bit error performance of the three receiver models that we consider. We also provide a tight lower bound in closed-form. Finally we extend the analysis to N-ary FSK to observe the improvement due to increased bandwidth use and transmitter/receiver complexity
Switching theory applied to wavelength routing networks by Richard A Barry( Book )

3 editions published in 1994 in English and held by 2 WorldCat member libraries worldwide

We consider the problem of interconnecting N local area networks (LANs) through a wavelength routing all optical network (wavelength-routing AON) supporting F wavelengths at R b/s per wavelength. A wavelength-routing AON is one in which the path of a signal is a function only of the signal wavelength and the origin of the signal. We allow the possibility of wavelength changing so that a signal may arrive at a destination on a different wavelength than it originated on. Furthermore, we assume a slotted system, where each wavelength supports T periodic time slots. A session, i.e. connection between a transmitter and a receiver, is assumed to require one frequency-time slot of bandwidth, i.e. R/T b/s. Each LAN has one outgoing fiber, one incoming fiber, and an unspecified but large number of users. The outgoing (incoming) fiber of a LAN is connected by a broadcast star to all the transmitters (receivers) of that LAN. We assume that there is exactly one active session between each pair of LANs. Therefore the network supports N-squared sessions. Define the capacity, C, as the largest value of N-squared possible as a function of F and T
On the bit error rate of lightwave systems with optical amplifiers by Pierre A Humblet( Book )

2 editions published in 1991 in English and held by 1 WorldCat member library worldwide

We revisit the problem of evaluating the performances of communications systems with optical amplifiers and a wideband optical filter. We compute the exact probability of error and the optimal threshold and compare them with those predicted by Gaussian approximations for ASK, FSK or DPSK modulations, both for ideal photodetectors and for the case where shot noise is significant
