“…It makes use of unbalanced Mach-Zehnder interferometers. provide higher channel counts within transmission bands [3] (Figure 4). When used as a multiplexing device, an "even" set of periodic channels are permitted to pass through one input, and the "odd" set of periodic channels are permitted to pass through the other.…”

The need for flexible optical network architectures will increase as network operators attempt to support dynamic bandwidth demands. A very flexible broadband wavelength multiplexer with unique characteristics has been developed for use in flexible optical networks. This technology innovation allows flexible multiplexing of single channel traffic and multi-wavelength traffic onto one fiber. Multi-wavelength traffic spaced 100 Ghz apart modulated at 10 Gb/s is multiplexed while introducing minimal optical impairments. A significant reduction in interchannel crosstalk-like noise generated by interactions of closely spaced channels in multi-wavelength traffic is achieved.

“…Today's DWDM systems with interleavers can be upgraded with much narrower channel spacings and more channel counts for very large capacity applications. [1][2][3] Several techniques have already been proposed for implementing optical interleavers, and these include the F 3 T interleaver, [1][2][3] Michelson-Gires-Tournois interleaver, 4 Birefrigent…”

All-fiber Fourier filter flat-top interleaver design with specified performance parameters

A minimax method for designing a Fourier filter flat-top (F 3 T) interleaver is proposed and demonstrated. Given a passband range, the proposed minimax method is able to produce an F 3 T interleaver with a specified bandwidth, minimal insertion loss, and higher isolation. In comparison with current interleaver design methods, the proposed approach has the advantage that the design parameters and the performance parameters of the interleaver can be obtained analytically.

“…One or both of the core/cladding is doped to provide a very slight difference (<1%) in refractive index that acts to confine propagating optical energy to the core. These low-contrast waveguides are capable of achieving very low attenuation per centimeter (0.05 dB/cm or better) with sufficiently low polarization effects as to make them suitable for telecommunications applications [1]. In fact, low-contrast SiO 2 -based waveguides have become the de-facto standard for telecom integrated optic circuits.…”

Surface waveguides for telecom applications are typically SiO 2 -based, low-contrast surface waveguides because these applications are dominated by the need for low optical attenuation and low polarization effects across the 1300-1600 nm band. Conventional waveguides, however, comprise films as thick as 20 micron and have minimum bend radii of tens of millimeters. These factors make conventional waveguide circuits large and expensive, and this has limited their use to relatively few applications.In the integrated optical sensing field, the waveguides typically used are (very) high-contrast waveguides. Here, especially Si 3 N 4 -core waveguides are well-known to offer much smaller bending radii (tens to hundreds of microns) due to stronger mode confinement to the core. Since they also typically comprise sub-micron core-thickness and cladding-thickness of only a few microns, high-contrast waveguides promise lower cost than low-contrast waveguides. Their use in telecom applications has been limited, however, due to strong polarization effects. Recently, LioniX, BV has developed the TriPleX™ waveguide, which promises to be a well-suited platform for both telecom and sensing applications and is based on low-cost, CMOS-compatible LPCVD processing. TriPleX™ technology provides highcontrast waveguides with very low channel attenuation and modal birefringence that is controlled through waveguide design alone. Early experiments on typical geometries show promising waveguide characteristics (attenuation « 0.5 dB/cm, IL ≤ -2 dB, PDL « 1 dB, bend radius « 1 mm).In this paper, we present the characteristics of this TriPleX TM technology, and show devices that have demonstrated utility in telecom and/or sensor applications using medium and high-contrast waveguides. Experimental results for an MZI-based sensor platform, suitable for liquid or gaseous sensing, are also provided.
