摘要： A transition part (1) between two optical waveguides (2,3) with different index contrast is characterised in that the transition part (1) includes a non-adiabatically up-tapered longitudinal section (8), and in that the transition (7) between the two waveguides (2,3) is arranged after the up-tapered longitudinal section (8) as seen along the main direction (L) of propagation of the light. A method of manufacturing the transition part is also described.

摘要： A waveguide for the extraction of light at low levels of reflection arranged to guide light from an electro-optical component on a chip to a facet on the chip for extraction includes a first part and a second part. The first part (4) is extended, the second part (5) includes a surface (JK) through which the light exits from the waveguide (1). A non-adiabatic longitudinal section (GHLM) is located after the first part (4) but before the surface (JK) in the direction of propagation of the light, and the surface (JK) forms in the plane of the chip a first angle (V1) with the optical axis (A) of the first part (4) that lies between 5 and 80 degrees.

摘要： An optical light splitter includes or is connected to at least two input waveguides (4; 6, 7; 18, 19; 32,33) for light. The light splitter (1, 2, 30, 40), on the side opposite to the input waveguide or input waveguides (4; 6, 7; 18, 19; 32, 33; 41, 42) transitions into at most one output waveguide (8, 10, 20, 34) in the direction of propagation of the incoming light. A surface (14, 25, 31, 45) is present set at an angle to the direction of propagation of the light in that part of the light splitter that is opposite to the input waveguide or input waveguides, the surface is present where the light splitter has an image from incoming light, and internal corners are not present in the part.

摘要： Method for producing a modulated grating for an optimal reflection spectrum, which grating is a multiple wavelength reflector. The method includes the following steps: a) Determining wavelengths to be reflected b) Calculating a preliminary grating c) Comparing the reflection spectrum ro(f) with the characteristics of the wanted modulated grating d) Differences lead to a directional change of ro(f) e) Calculating a target function G(z) f) Changing the grating (zk) depending on the real and imaginary part of G(z) g) Repeating steps c) to f) until the grating reflects the predetermined wavelengths.
