    摘要: The present disclosure describes techniques for fabricating a multi-level structure. For example, in accordance with some implementations, the disclosure describes techniques for fabricating a multi-level master from which optical elements can be replicated either directly or by way of a sub-master. The disclosure also describes multi-level optical elements and processes for making them.
