Yes, there is a term for that. There is a sub-genre called ["hard science fiction"](https://en.wikipedia.org/wiki/Hard_science_fiction) ([tag:hard-sci-fi]) which tends to have real scientific principles at its foundation, and many of which use technical jargon or get very into the details of how their fictional science works practically. The term is fairly useful for finding authors specifically in that sub-genre, and not just sci-fi authors in general. Aside from the Wikipedia page linked earlier, there's a number of resources and fanpages devoted towards the sub-genre. That is, it's the _de facto_ terminology (in English), for what you're looking for.
