“…The deep ridge waveguide makes the bending radii only 250 m, enabling us to fabricate extremely small InP AWG. It has been reported that a 40 channel InP AWG was integrated with 40 EMLs, including 241 discrete function components on a single monolithic InP chip [26]. Figure 10 shows a 10 channel 200 GHz InP , and the insertion loss is about 16 dB at the center output port.…”

We summarized the design, fabrication challenges and important technologies for multi-wavelength laser transmitting photonic integration. Technologies discussed include multi-wavelength laser arrays, monolithic integration and modularizing coupling and packaging. Fabrication technique requirements have significantly declined with the rise of reconstruction-equivalent-chirp and second nanoimprint mask technologies. The monolithic integration problem between active and passive waveguides can be overcome with Butt-joint and InP array waveguide grating technologies. The dynamic characteristics of multi-factors will be simultaneously measured with multi-port analyzing modules. The performance of photonic integration chips is significantly improved with the autoecious factors compensation packaging technique. photonic integration, laser, multi-wavelength Citation:Chen X F, Liu W, An J M, et al.

“…Even in the peculiar and harsh market environment that followed the telecom bubble, this was eventually achieved and today commercial devices and related network elements capable of broadly replacing analog amplification do exist [22] and despite DWDM conventional systems still represent overall the largest market segment and can prove advantageous in particular applications and network configurations, digital WDM networking is undoubtedly already a commercial reality in transport networks. The key behind such systems was optical integration based on InP technology with electronics processing still based on a separate Si or SiGe technology.…”

Broadband networks are among the fastest growing segment in telecom. The initial and still very significant push originated with xDSL technologies and indeed a significant amount of research and development is still occurring in this field with impressive results and allowing for a remarkable use of the installed copper infrastructure way beyond its originally planned bandwidth capabilities. However it is clear that ultimately a more suitable fiber based infrastructure will be needed in order to reduce both operational and network technology costs. Such cost reduction in inevitable as the added value to end users is only related to services and these cannot be priced outside a sensible window, whilst the related bandwidth increase is much more dramatic and its huge variability must be met with little or no cost impact by the network and its operation. Fiber in access has indeed the potential to cope with a huge bandwidth demand for many years to come as its inherent bandwidth capabilities are only just tapped by current service requirements. However the whole technology supply chain must follow in line. In particular optical technology must brace itself to cope with the required much larger deployment and greater cost effectiveness, whilst at the same time deliver performance suitable to the bandwidth increase offered in the longer term by the fiber medium. This paper looks at this issues and debates the opportunities for a new class of optical devices making use of the progress in optical integration

“…As a potentially enabling microphotonics platform, PLC technology is being driven by the needs of cost, coupling loss (CL), and footprint reduction with increasing functionality [1]. Therefore, the coupling between fibers and the input/output ports of PLC-based chips becomes a key technology.…”

A 3-D equivalent rectangle approximation staircase concatenation method to analyze the optical mode evolution in a wedge-shaped fiber (WSF) is proposed in this paper. A scheme with an axial gradient-index (AGRIN) lens between the WSF and InP-based planar lightwave circuit (PLC) chip, yielding higher transmission efficiency than those with two cascaded lenses and one radial GRIN lenses, by 2.282 and 7.816 dB, respectively, is devised and experimentally demonstrated. The WSF-AGRIN-PLC-single-mode fiber coupling linkage supplies a preferable solution for solving the problem of index mismatching in fiber-toInP-based PLC assembly to achieve a high-efficiency connection.
