The invention provides integrated optical matching elements for use in integrated optical devices. The matching elements each comprise one or more lenses. The lenses may have low index contrast with the surrounding medium. Required dioptric power is achieved by using a train of lenses. Optical matching elements according to the invention can be used to enhance the optical coupling between channel waveguides and slab waveguides. The insertion loss of devices such as optical power splitters, optical couplers and arrayed waveguide grating routers can be reduced by incorporating optical matching elements according to the invention.

Techniques for inferring data to improve the accuracy and completeness of information retrieval are disclosed herein. In some embodiments, a data inference system detects a lack of employment type data for a profile of a user on an online service, with the employment type data identifying at least one type of employment in which the user is interested. In some embodiments, based on the detecting of the lack of employment type data for the profile of the user, the data inference system generates the employment type data based on an inference model and inference data, with the inference data comprising at least one of profile data of the user and a history of the user's interactions with the online service, and the data inference system performs a function of the online service using the generated employment type data.
