This is done through :caption property:
(org-element-property :caption some-element)
Note that when non nil, the value of this property is a list of two
secondary strings: CAR is the regular caption while CDR in the
(optional) short caption. Also, don't forget to send them through
`org-export-data'. Here's a snippet illustrating this:
#+begin_src emacs-lisp
(let ((caption (org-element-property :caption element)))
;; This how you get the long caption.
(org-export-data (car caption) info)
;; This is how you get the short caption or the empty string.
(org-export-data (cdr caption) info))
#+end_src

You can also write raw Groff code within #+begin_groff...#+end_groff,
provided that you modify `org-element-block-name-alist' accordingly and
define a transcoder for export blocks like the following:
#+begin_src emacs-lisp
(defun org-e-groff-export-block (export-block contents info)
"Transcode a EXPORT-BLOCK element from Org to GROFF.
CONTENTS is nil. INFO is a plist holding contextual information."
(when (equal (org-element-property :type export-block) "GROFF")
(org-remove-indentation (org-element-property :value export-block))))
#+end_src
