“…Although, external optical feedback resistant DFB [18] and VCSEL [20] lasers were developed and recently demonstrated, their fabrication cost remains high. Floor-free transmissions have already been reported with either VCSELs [19], [20] or DFB lasers [21], [22] at 2.5 Gbit/s under strong feedback regime. In this section, we report on the first transmission performances of DM lasers under optical feedback.…”

The wavelength spectra of ridge waveguide Fabry Perot lasers can be modified by perturbing the effective refractive index of the guided mode along very small sections of the laser cavity. One way of locally perturbing the effective index of the lasing mode is by etching features into the ridge waveguide such that each feature has a small overlap with the transverse field profile of the unperturbed mode, consequently most of the light in the laser cavity is unaffected by these perturbations. A proportion of the propagating light is however reflected at the boundaries between the perturbed and the unperturbed sections. Suitable positioning of these interfaces allows the mirror loss spectrum of a Fabry Perot laser to be manipulated. In order to achieve single longitudinal mode emission, the mirror loss of a specified mode must be reduced below that of the other cavity modes. Here we review the latest results obtained from devices containing such features. These results clearly demonstrate that these devices exceed the specifications required for a number of FTTH and Datacomms applications, such as GEPON, LX4 and CWDM. As well as this we will also present initial results on the linewidth of these devices.

“…A record 55-Gb/s transmission of 0.85-μm OOK VCSEL signals was also demonstrated by using the electrical equalization at both the transmitter and receiver sides [3]. For 1.5-μm VCSELs, error-free transmissions of 10-Gb/s OOK signals over 10-and 40-km SSMF were reported by using the electrical equalization at the receiver [19].…”

“…Electrical equalization is another technique which can be exploited to compensate for fiber dispersion of VCSEL links [3], [11], [18], [19]. It has been shown that a 32-Gb/s 4-PAM signal can be transmitted over MMF links by using a 0.85-μm VCSEL together with a transversal electrical filter at the transmitter side [11].…”

We evaluate the possibility of realizing optical access networks using 1.5-μm vertical-cavity surface-emitting lasers (VCSELs) in the on-off keying (OOK) and four-level pulse amplitude modulation (4-PAM) formats. In order to maximize the power budget of the networks, we optimize the extinction ratio of the 10.7-and 21.4-Gb/s signals and exploit the electrical equalization at the receiver. The experimental comparison made at 10.7 Gb/s shows that the OOK format vastly outperforms the 4-PAM format in terms of tolerance to chromatic dispersion. For example, we achieve the 80-km transmission of the OOK signal over standard single-mode fiber (SSMF), but the maximum reach is halved when the 4-PAM signal is employed. Nevertheless, the 4-PAM format is still an effective way to double the data rate of the VCSEL links in optical access networks. We successfully transmit the 21.4-Gb/s 4-PAM signal generated by using the 1.5-μm VCSEL over 18-km long SSMF.

“…One of the techniques for the size and cost alleviation is the removal of inverse dispersion fiber (IDF) [25] and dispersion compensating modules (DCMs) [26]. Electronic-dispersion compensation (EDC) [27] and injection locking [28] schemes are previously used as dispersion compensators to enhance the reach of a 10 Gb/s VCSEL, all these methods enhance the complexity and power consumption of the optical fiber system. The adopted method presents an effective way to extend the dispersion-limited distance of VCSEL without reducing bit error rate (BER) and sensitivity of received signal.…”

This paper presents a new approach to maximize the dispersion-limited distance of vertical cavity surface emitting lasers (VCSELs) operating at 1550.127 nm with 10 Gb/s bit rate. Optical non return to zero (NRZ) signal is generated by using an optical band pass filter (OBPF) along with MachZehnder interferometer (MZI) at the output of VCSEL. A third order super-Gaussian and fourth order Butterworth filters are used as optical filters. The dependence of bit error rate (BER), the eye opening and transmission distance on variations in the optical filter and MZI parameters is investigated. The numerical results signify that with the proposed scheme one can enhance the single mode fiber (SMF) link-length to 127 km in the absence of electrical or optical dispersion compensation methods. Results are compared between the proposed method and transmitters implemented with VCSEL diode. General TermsOptical communications.
