Examples herein relate to optical modules. In particular, implementations herein relate to optical modules that include top-emitting VCSELs and/or top-entry photodetectors. The optical modules include a first interposer having opposing first and second sides and a second interposer having opposing first and second sides. The optical modules include a plurality of top-emitting vertical-cavity surface-emitting lasers (VCSELs) coupled to the second interposer and a plurality of electrical conductors forming electrical paths between electrical contacts of the top-emitting VCSELs and the second side of the second interposer. The VCSELs are configured to emit optical signals having different wavelengths. The optical signals are configured to be combined and transmitted over a single optical fiber.
