Abstract: An optical fiber mode coupling device, capable of being readily connected to a conventional optical fiber with a high degree of ruggedness, is provided. The inventive mode coupling device only allows transmission of at least one supported fiber mode therethrough, and is preferably configured to maximize the coupling, of at least one desired fiber mode, to the at least one supported fiber mode. Advantageously, the inventive mode coupling device is capable of performing the functions of a mode filter for the signal entering its first end, or serving as a mode conditioner for the signal entering its opposite second end. Thus, in one practical application thereof, the novel mode coupling device functions as a mode filter by maximizing the coupling between at least one desired fiber mode of a multi-mode input signal entering the device's first end, and at least one supported mode of the device, to produce an output signal at the device's second end that comprises at least one predetermined fiber mode, corresponding to at least one desired fiber mode. In another practical application thereof, the novel mode coupling device functions as a mode conditioner by maximizing the coupling between an input signal, comprising at least one predetermined fiber mode, that enters the device's second end, and, and at least one supported mode of the device, to produce an output signal at the device's first end that comprises at least one desired fiber mode, corresponding to a conditioned at least one predetermined fiber mode.

Abstract: Provided are methods of forming an optical coupler. The method includes forming a first waveguide and an in-plane tapered layer on a silicon layer, forming a mask with first and second openings. The first opening is formed between the in-plane tapered layer and the second opening, and the second opening extends from the first opening with a gradually narrowing width. Thereafter, a planar waveguide and a three-dimensional tapered layer are simultaneously formed in the first and second openings, respectively. The planar waveguide has a substantially uniform thickness, and the three-dimensional tapered layer has a thickness gradually increasing with a decrease of the width thereof.

Abstract: Optical interfaces that may be employed between large-core optical fibers and chip-scale optoelectronic devices. Described herein are couplers that improve the tolerance of misalignment when a single mode (SM) fiber is used as waveguide input. This enables the possibility of passive/automatic alignment and therefore reduces the production cost. The coupler also serves as a spot-size converter that reduces the spot size and is suitable for applications where a waveguide mode with small cross-section area is of particular importance. One such example can be a waveguide-based SiGe or III-V semiconductor photodetector in which the vertical size of its waveguide mode should be as small as few microns.
