Please avoid any interior doors faced with tropical wood. I have been on the Lenfex site and it appears that a number of their doors have rainforest wood veneers, thus helping speed the destruction of tropical forests.

The second door in the post above appears to me to be African mahogany (although it might be walnut).

An interesting place to look is with cabinetry manufacturers. I know that Woodharbor, based out of Iowa, makes interior doors to match their cabinets, and those are considered semi-custom. You can choose your profile (raised panel, flat panel, etc.), edge detail (plain edge, mission edge, etc.), wood species (maple, cherry, mdf, etc.), finish (primed, stained, stained with glaze, or custom finish), hinge color, etc. They come as slabs or prehung, and can also have glass panels, including laminated or patterned glass, which can really add to the modern look. I know you can create a much more modern look than they display on their website, because they typically aren't after the modern market.

If you click on 'flat-panel doors,' then on 'Fairmont,' there is a single flat-panel door available, similar to the one you pictured.

Hope this helps!

Debbie Travis took a $20 hollow slab door, flat-panel, and cut out rectangular holes in it. She then put in some frosted pyrex glass (you can get spray-on frost) sections. The result was a door straight from the mod 70s. Very cool and very economical!

I'm going to veneer my doors with 1/4 inch veneered plywood.
The additional thickness from the plywood will be eaten up by the framing around the door, and go unnoticed. I will just have to lay down a band of real 1/16 or 1/32 veneer down the side where the clasping mechanism runs.
If you opt to do this, make sure that the additional bulk doesn't prevent the door from opening by butting up against the framing.
