    Abstract: The invention relates to an optical filter and a method for its production, and to a device for the examination of the spectral and spatial distribution of an electromagnetic radiation irradiated from an object. The invention is based on the task of providing an optical filter of the above described type that is inexpensive to produce, which can be used to detect a plurality of wavelengths, in which, however, tuning of the DBR mirrors by means of displacement is not necessary. Furthermore, a method for the production of such a filter is provided. According to a first aspect of the present invention this task is solved by a method for the production of an optical filter array having two DBR mirrors, and a cavity present between the same, comprising cavity sections having a plurality of different heights, each forming one Fabry Perot filter element, characterized by the following steps: applying a first DBR mirror onto a substrate, forming of a layer comprised of a cavity material on the DBR mirror, wherein this layer is equipped with a plurality of cavity sections forming the filter elements by means of utilizing a nanoimprint method, and applying the second DBR mirror on the cavity material having a structuring that is defined by the different heights of the cavity sections.

    Abstract: The invention discloses a multi-wavelength semiconductor light source comprising a plurality of semiconductor light sources mounted on a silicon sub-carrier and emitting radiation spanning a wavelength range. In preferred embodiments, these sources are configured in a linear and circular array. The radiation is coupled to a waveguide array disposed on the same silicon subcarrier, with a lower cladding of silicon dioxide and deposited core layer which is preferably the spin-on epoxy resin SU-8. Output from the waveguide array provides a compact multi-wavelength laser source with wide tuning range via a plurality of laser sources. An output spatial span of the waveguide array is smaller than an input spatial span and sufficiently small to probe the properties of a sample. A compact system for optical spectroscopy is constructed from the multi-wavelength semiconductor light source, a means for directing radiation from the source to a sample, and an optical detector configured to detect one of a radiation reflected from and transmitted through said sample. In various preferred embodiments, the semiconductor light sources can comprise lasers, light-emitting diodes, and superluminescent diodes.The system for optical spectroscopy can be used in a variety of applications including the analysis of in-vivo human tissue, agricultural samples, and pharmaceutical samples. Typical wavelength ranges for these and other applications include 650-1000 nm, 700-1700 nm, and 1100-2500 nm.

    Abstract: In a spectroscopy module 1, a light passing hole 50 through which a light L1 advancing to a spectroscopic portion 4 passes is formed in a light detecting element 5. Therefore, it is possible to prevent the relative positional relationship between the light passing hole 50 and a light detecting portion 5a of the light detecting element 5 from deviating. Moreover, the light detecting element 5 is bonded to a front plane 2a of a substrate 2 with an optical resin adhesive 63. Thus, it is possible to reduce a stress generated onto the light detecting element 5 due to a thermal expansion difference between the light detecting element 5 and the substrate 2. Additionally, on the light detecting element 5, a first pool portion 101 is formed so as to be located at least between the light detecting portion 5a and the light passing hole 50 when viewed from a direction substantially perpendicular to the front plane 2a. Thus, when the light detecting element 5 is attached to the substrate 2 via the optical resin adhesive 63, the optical resin adhesive 63 is pooled to remain at the first pool portion 101. Thus, the optical resin adhesive 63 is prevented from penetrating into the light passing hole 50.
