An encoder for providing encrypted data for transmission via a transmission medium includes an encryption unit that is configured to encrypt data received at the encoder block by block and a processing unit. The processing unit is configured to randomly distribute an encrypted data block to a plurality of channels that are allocated to the transmission medium and to provide a sub-block, which includes part of the encrypted data block, to be transmitted via one of the channels, together with a channel identification allocated to the channel and a code value that is based on the encrypted data in the sub-block to be transmitted and the channel identification, for transmission via the allocated channel of the transmission medium.

What is shown is a method for manufacturing a semiconductor light source. The semiconductor light source has a substrate and a layer sequence arranged above the substrate, the same having a light-emitting layer and an upper boundary layer arranged above the light-emitting layer. The layer sequence is patterned in order to form a light-emitting stripe for defining the semiconductor light source and an alignment stripe, extending in parallel thereto, as a horizontal alignment mark at the same time. Then, a cover layer is applied on the patterned layer sequence and a part of the cover layer is removed in order to expose the alignment stripe and expose a region of the layer sequence outside the light-emitting stripe and spaced apart from a light-entrance edge or a light-exit edge of the light-emitting stripe as a vertical alignment mark.
