“…From the existing works focusing on reducing the TDM-PON cost, 12,20,21 we find that the most popular method of reducing TDM-PON cost is using colorless ONUs. But we must point out that the colorless ONUs were applied to WDM/TDM hybrid PONs in these existing works.…”

Abstract. As a promising technology for broadband communication, passive optical network (PON) has been deployed to support the last-mile broadband access network. In particular, time-division-multiplexing PON (TDM-PON) has been widely used owing to its mature technology and low cost. To practically implement TDM-PONs, the combination of intensity modulation and direct detection is a very promising technique because it achieves cost reduction in system installation and maintenance. However, the current intensity-modulation and direct-detection TDM-PON still suffers from some problems, which mainly include a high-power penalty, detrimental Brillouin backscattering (BB), and so on. Thus, using directly modulated lasers (DMLs) and colorless optical network units (ONUs), respectively, two intensity-modulation and direct-detection TDM-PON architectures are proposed. Using VPI (an optical simulation software developed by VPIphotonics company) simulators, we first analyze the influences on DML-based intensity-modulation and direct-detection TDM-PON (system 1) performances, which mainly include bit error rate (BER) and power penalty. Next, the BB effect on the BER of the intensity-modulation and direct-detection TDM-PON that uses colorless ONUs (system 2) is also investigated. The simulation results show that: (1) a low-power penalty is achieved without degrading the BER of system 1, and (2) the BB can be effectively reduced using phase modulation of the optical carrier in system 2. © The Authors.Published by SPIE under a Creative Commons Attribution 3.0 Unported License.

“…On one side, some researches on reusing the wavelength from OLT via semiconductor optical amplifier (SOA), reflective SOA (RSOA), and SOA integrated with reflective electro-absorption modulator (SOA-REAM) [5][6][7][8] have been done, while power penalty is the serious problem for these applications. Hence, there is an idea for limiting the power penalty to put the laser at ONU side, such as tunable laser at ONU [10], however, it is too expensive to deploy at each ONU.…”

a b s t r a c tWe report a new scheme to support, cost efficiently, ultra-dense wavelength division multiplexing (UDWDM) for optical access networks. As validating experiment, we apply phase modulation of a reflective semiconductor optical amplifier (RSOA) at the ONU with a single DFB, and simplified coherent receiver at OLT for upstream. We extend the limited 3-dB modulation bandwidth of available uncooled To-can packaged RSOA ( $400 MHz) and operate it at 3.125 Gb/s with the optimal performance for phase modulation using small and large signal measurement characteristics. The optimal condition is selected at input power of 0 dB m, with 70 mA bias condition. The sensitivities at 3.125 Gb/s (at BER¼ 10 À 3 ) for heterodyne and intrady Q2 ne detection reach À 34.3 dB m and À 38.8 dB m, respectively.

“…At present, all of these elements are available in integrated form. It should be noted here that from the point of view of integrated solutions -the invention of the semiconductor optical amplifier (SOA) [3] was a real breakthrough, enabling both amplification of the optical signals with gain as high as 30 dB [4] and design of various types of integrated semiconductor lasers, described in the following part of this paper.…”

Abstract. In this work a brief review on photonic integrated circuits (PICs) is presented with a specific focus on integrated lasers and amplifiers. The work presents the history of development of the integration technology in photonics and its comparison to microelectronics. The major part of the review is focused on InP-based photonic integrated circuits, with a short description of the potential of the silicon technology. A completely new way of fabrication of PICs, called generic integration technology, is presented and discussed. The basic assumption of this approach is the very same as in the case of electronic circuits and states that a limited set of standard components, both active and passive, enables designing of a complex, multifunctional PIC of every type. As a result, functionally advanced, compact, energy efficient and cost-optimized photonic devices can be fabricated. The work presents also selected examples of active PICs like multiwavelength laser sources, discretely tunable lasers, WDM transmitters, ring lasers etc.
