This paper presents a theoretical and experimental study of nonlinear effects in distributed Bragg reflector (DBR)type tunable lasers, which are responsible for asymmetric spectral or power characteristics, and for hysteresis phenomena. We propose an optimized DBR semiconductor optical amplifier design that suppresses these effects, making the control simpler and more reliable, while maintaining the same performances as a DBR (16 nm tuning, 40 dB side mode suppression ratio, 20 mW coupled output power). Aiming to reach C-band tuning range with only one Bragg current control and reduced nonlinear effects, a new double Bragg DBR laser is proposed.Index Terms-Four-wave mixing (FWM), monolithically integrated sources, semiconductor tunable lasers.

Abstract-In this paper, we present a new concept of optical packet/burst switching suitable for generalized multiprotocol label switched (GMPLS)-based optical networks. In such networks, optical labeled switched Paths are being established in a similar way as label-switched paths in MPLS. We use a wavelength label as well as an orthogonally modulated label, with respect to the payload modulation format, and which is encoded using either frequency-shift keying (FSK) or differential phase-shift keying (DPSK). Wavelength is used for switching in the node, whereas the orthogonal label defines the label-switched path. We present both simulation and experimental results to assess transmission performance of the proposed combined modulation scheme. In addition, we propose a suitable optical node architecture that can take advantage of this stacked label concept. Toward this, we use widely tunable wavelength converters to efficiently route IM/FSK (or IM/DPSK) optically labeled packets in an arrayed-waveguide grating (AWG)-based node structure. We present performance simulation results in terms of packet loss ratio and internal block probability. Internal blocking is an inherent problem of AWG optical routers, and a specific wavelength assignment algorithm has been developed to minimize it. Finally, the feasibility of IM/FSK transmission is experimentally demonstrated over an 88-km single-mode fiber span, and novel aspects of FSK generation and detection techniques are presented.Index T...

“…The only problem with these lasers is the need to control three currents to obtain a specified output power and wavelength; this requires complex control locking algorithm [3]. The reduction of one control current in two-section (2S) DBR devices mitigates this problem but due to their discontinuous tuning characteristic, the 2S-DBR lasers do not match the desired wavelengths only by current tuning; usually, a temperature control is also used in these cases [4]. In this paper we show that by a proper laser design the ITU wavelengths can be matched only by current tuning of 2S-DBR lasers, whereas the temperature can be used eventually to overcome the technological tolerances of the design parameters.…”

The paper deals with the description of a simulation procedure for the design and the optimisation of tunable multisection distributed Bragg reflector (DBR) lasers. In particular a special attention is dedicated to the design of twosection DBR lasers with operating wavelengths matching the ITU frequency standard grid only by grating current tuning. To our knowledge this is the first time that by a proper design procedure this condition has been satisfied.
