A vertical cavity surface emitting laser (VCSEL) device includes a substrate, a first mirror layer, a tunnel junction layer, a second mirror layer, an active layer, an oxide layer and a third mirror layer sequentially stacked with one another. The first mirror layer and the third mirror layer are N-type distributed Bragg reflectors (N-DBR), and the second mirror layer is P-type distributed Bragg reflector (P-DBR). The tunnel junction layer is provided for the VCSEL device to convert a part of the P-DBR into N-DBR to reduce the series resistance of the VCSEL device, and the tunnel junction layer is not used as current-limiting apertures. This disclosure further discloses a VCSEL device manufacturing method with the in-situ and one-time epitaxy features to avoid the risk of process variation caused by moving the device into and out from an epitaxial cavity.
